Enum hotshot_query_service::availability::Fetch

source · 
pub enum Fetch<T> {
+    Ready(T),
+    Pending(BoxFuture<'static, T>),
+}
Expand description

An in-progress request to fetch some data.

+

A Fetch represents the period of uncertainty after some data has been requested, before it +is known whether that data exists locally or must be retrieved from an external source (or +whether we must wait for the data to be created in the first place).

+

For data that is already available locally, a request for that data may return Fetch::Ready +with the data itself. Otherwise, the request will return Fetch::Pending with a future that +will resolve once the data is available.

+

Depending on the context, Fetch can behave a bit like a Future or a bit +like a Result. Therefore, it implements IntoFuture, so it can be awaited (this is the +same as calling resolve) and it implements methods context +and with_context, which make it easy to convert a Fetch to a +Result, mimicking the methods from Snafu traits OptionExt and +ResultExt.

Implementations§

source§

impl<T> Fetch<T>

source

pub fn try_resolve(self) -> Result<T, Self>

Get the requested data if it is available immediately.

+

If the requested data is not immediately available, Err(self) is returned so that the +Fetch object may be used again.

+
source

pub fn context<C, E>(self, context: C) -> Result<T, E>where + C: IntoError<E, Source = NoneError>, + E: Error + ErrorCompat,

Convert this Fetch to a Result with the provided error context.

+

The result indicates whether the requested data is immediately available. If it is, Ok +is returned. Otherwise, an error is created from context using Snafu.

+
source

pub fn with_context<F, C, E>(self, context: F) -> Result<T, E>where + F: FnOnce() -> C, + C: IntoError<E, Source = NoneError>, + E: Error + ErrorCompat,

Convert this Fetch to a Result with the provided error context.

+

The result indicates whether the requested data is immediately available. If it is, Ok +is returned. Otherwise, an error is created from context using Snafu.

+
source§

impl<T: Send + 'static> Fetch<T>

source

pub async fn resolve(self) -> T

Wait for the data to become available, if it is not already.

+
source§

impl<T: 'static> Fetch<T>

source

pub fn map<F, U>(self, f: F) -> Fetch<U>where + F: 'static + Send + FnOnce(T) -> U,

Transform the result of this fetch.

+

If the requested data is already available, f will be applied immediately. Otherwise, f +will be saved and applied after the pending future resolves.

Queries for HotShot chain state.

+
The availability API provides an objective view of the HotShot blockchain. It provides access
+only to normative data: that is, data which is agreed upon by all honest consensus nodes and
+which is immutable. This means access to core consensus data structures including leaves,
+blocks, and headers, where each query is pure and idempotent. This also means that it is
+possible for a client to verify all of the information provided by this API, by running a
+HotShot light client and downloading the appropriate evidence with each query.

+
This API does not provide any queries which represent only the current state of the chain or
+may change over time, and it does not provide information for which there is not (yet) agreement
+of a supermajority of consensus nodes. For information about the current dynamic state of
+consensus and uncommitted state, try the status API. For information about the
+chain which is tabulated by this specific node and not subject to full consensus agreement, try
+the node API.

An interface for querying a HotShot blockchain.

+
This interface provides expressive queries over all the data which is made available by HotShot
+consensus. The data exposed by this interface consists entirely of normative data: data which
+every correct HotShot node or light client will agree on, and which is guaranteed by consensus
+to be immutable. This immutability has an interesting consequence: all of the methods exposed by
+this trait are pure: given equivalent inputs, the same method will always return equivalent
+outputs1.

+
This purity property has a further consequence: none of the methods defined here can fail! Even
+if you query for a block at a position past the end of the current chain – a block which does
+not exist yet – the query will not fail. It will return an in-progress Fetch which, when it
+finally does resolve, resolves to the unique block at that position in the chain. All subsequent
+queries for the same position will eventually resolve to the same block.

+
In other words, the abstraction is that of an infinitely long chain which exists statically, in
+its entirety, at all times. In reality, of course, this chain is being produced incrementally
+and has a finite length at any given time. But all this means is that some queries may take a
+long time to resolve while others may resolve immediately.

+
  1. The data returned by these methods are wrapped in Fetch, which does not implement
+[PartialEq]. So to speak of equivalent outputs, we need to define an equivalence
+relation on Fetch<T>. The relation we will use is defined when T: PartialEq, and
+defines two fetches f1 and f2 as equivalent when f1.await == f2.await. That is,
+depending on when you call a certain method, you may or may not get a response
+immediately. But whenever you do get the data you requested, it is unique for that
+combination of inputs. ↩

source · 
pub type SqlDataSource<Types> = FetchingDataSource<Types, SqlStorage, ()>;
Expand description

A data source for the APIs provided in this crate, backed by a remote PostgreSQL database.

+

Administration

+

This data source will automatically connect to and perform queries on a remote SQL database. +However, administration of the database, such as initialization, resetting, and backups, is +left out of the scope of this implementation, and is expected to be performed manually using +off-the-shelf DBMS adminstration tools. The one exception is migrations, which are handled +transparently by the SqlDataSource.

+

Schema

+

All the objects created and used by SqlDataSource are grouped under a schema for easy +management. By default, the schema is named hotshot, and is created the first time a +SqlDataSource is constructed. The name of the schema can be configured by setting +Config::schema.

+

Initialization

+

When creating a SqlDataSource, the caller can use Config to specify the host, user, and +database to connect to. As such, SqlDataSource is not very opinionated about how the +Postgres instance is set up. The administrator must simply ensure that there is a database +dedicated to the SqlDataSource and a user with appropriate permissions (all on SCHEMA and +all on DATABASE) over that database.

+

Here is an example of how a sufficient database could be initialized. When using the standard +postgres Docker image, these statements could be placed in +/docker-entrypoint-initdb.d/init.sql to automatically initialize the database upon startup.

+
CREATE DATABASE hotshot_query_service;
+\connect hotshot_query_service;
+CREATE USER hotshot_user WITH PASSWORD 'password';
+GRANT ALL ON SCHEMA public TO hotshot_user;
+GRANT ALL ON DATABASE hotshot_query_service TO hotshot_user WITH GRANT OPTION;
+
+

One could then connect to this database with the following Config:

+ +
Config::default()
+    .host("postgres.database.hostname")
+    .database("hotshot_query_service")
+    .user("hotshot_user")
+    .password("password")
+

Resetting

+

In general, resetting the database when necessary is left up to the administrator. However, for +convenience, we do provide a reset_schema option which can be used to +wipe out existing state and create a fresh instance of the query service. This is particularly +useful for development and staging environments. This function will permanently delete all +tables associated with the schema used by this query service, but will not reset other schemas +or database.

+

Migrations

+

For the SqlDataSource to work, the database must be initialized with the appropriate schema, +and the schema must be kept up to date when deploying a new version of this software which +depends on a different schema. Both of these tasks are accomplished via migrations.

+

Each release of this software is bundled with a sequence of migration files: one migration for +each release that changed the schema, including the latest one. Replaying these SQL files +against a database with an older version of the schema, including a completely empty database, +will bring it up to date with the schema required by this version of the software. Upon creating +an instance of SqlDataSource and connecting to a database, the data source will +automatically fetch the current version from the database and, if it is old, replay the +necessary migration files.

+

Custom Migrations

+

In keeping with the philosophy of this crate, SqlDataSource is designed to be +extensible and composable. When extending the provided APIs with +new, application-specific queries, it will often be desirable to alter the schema of the +database in some way, such as adding additional columns to some of the tables or creating new +indices. When composing the provided APIs with additional API modules, it may also be desirable +to alter the schema, although the changes are more likely to be completely independent of the +schema used by this data source, such as adding entirely new tables.

+

In either case, the default schema can be modified by inserting additional migrations between +the migrations distributed with this crate. The new migrations will then automatically be +replayed as necessary when initializing a SqlDataSource. New custom migrations can be +added with each software update, to keep the custom data up to date as the default schema +changes.

+

Custom migrations can be inserted using Config::migrations. Each custom migration will be +inserted into the overall sequence of migrations in order of version number. The migrations +provided by this crate only use version numbers which are multiples of 10, so the non-multiples +can be used to insert custom migrations between the default migrations. You can also replace a +default migration completely by providing a custom migration with the same version number. This +may be useful when an earlier custom migration has altered the schema in such a way that a later +migration no longer works as-is. However, this technique is error prone and should be used only +when necessary.

+

When using custom migrations, it is the user’s responsibility to ensure that the resulting +schema is compatible with the schema expected by SqlDataSource. Adding things (tables, +columns, indices) should usually be safe. Removing, altering, or renaming things should be done +with extreme caution.

+

It is standard to store custom migrations as SQL files in a sub-directory of the crate. For ease +of release and deploymenet, such directories can be embedded into a Rust binary and parsed into +a list of Migration objects using the include_migrations macro.

+

It is also possible to take complete control over migrating the schema using +Config::no_migrations to prevent the SqlDataSource from running its own migrations. The +database administrator then becomes responsible for manually migrating the database, ensuring the +schema is up to date, and ensuring that the schema is at all times compatible with the schema +expected by the current version of this software. Nevertheless, this may be the best option when +your application-specific schema has diverged significantly from the default schema.

+

Synchronization

+

SqlDataSource implements VersionedDataSource, which means +changes are not applied to the underlying database with every operation. Instead, outstanding +changes are batched and applied all at once, atomically, whenever +commit is called. Outstanding, uncommitted changes can +also be rolled back completely using revert.

+

Internally, the data source maintains an open Transaction whenever there are outstanding +changes, and commits the transaction on commit. The +underlying database transaction can be accessed directly via transaction, +which makes it possible to compose application-specific database updates atomically with updates +made by the SqlDataSource itself. This is useful for extension and +composition.

+

Extension and Composition

+

SqlDataSource is designed to be both extensible (so you can add additional state to the API +modules defined in this crate) and composable (so you can use SqlDataSource as one component +of a larger state type for an application with additional modules).

+

Extension

+

It is possible to add additional, application-specific state to SqlDataSource. If the new +state should live in memory, simply wrap the SqlDataSource in an +ExtensibleDataSource:

+ +
type AppState = &'static str;
+
+let data_source: ExtensibleDataSource<SqlDataSource<AppTypes>, AppState> =
+    ExtensibleDataSource::new(SqlDataSource::connect(config).await?, "app state");
+

The ExtensibleDataSource wrapper implements all the same data +source traits as SqlDataSource, and also provides access to the AppState parameter for use +in API endpoint handlers. This can be used to implement an app-specific data source trait and +add a new API endpoint that uses this app-specific data, as described in the +extension guide.

+

If the new application-specific state should live in the SQL database itself, the implementation +is more involved, but still possible. Follow the steps for +custom migrations to modify the database schema to account for the new +data you want to store. You can then access this data through the SqlDataSource using +query to run a custom read-only SQL query or transaction +to execute a custom atomic mutation of the database. If you use +transaction, be sure to call +commit when you are ready to persist your changes.

+

You will typically use query to read custom data in API endpoint handlers and +transaction to populate custom data in your web server’s update loop.

+

Composition

+

Composing SqlDataSource with other module states is fairly simple – just +create an aggregate struct containing both SqlDataSource and your additional module +states, as described in the composition guide. If the additional modules +have data that should live in the same database as the SqlDataSource data, you can follow +the steps in custom migrations to accomodate this. When modifying that +data, you can use transaction to atomically synchronize updates to the +other modules’ data with updates to the SqlDataSource. If the additional data is completely +independent of HotShot query service data and does not need to be synchronized, you can also +connect to the database directly to make updates.

+

In the following example, we compose HotShot query service modules with other application- +specific modules, synchronizing updates using transaction.

+ +
struct AppState {
+    hotshot_qs: SqlDataSource<AppTypes>,
+    // additional state for other modules
+}
+
+async fn init_server(
+    config: Config,
+    mut hotshot: SystemContextHandle<AppTypes, AppNodeImpl>,
+) -> Result<App<Arc<RwLock<AppState>>, Error>, Error> {
+    let mut hotshot_qs = SqlDataSource::connect(config).await.map_err(Error::internal)?;
+    // Initialize storage for other modules, using `hotshot_qs` to access the database.
+    let tx = hotshot_qs.transaction().await.map_err(Error::internal)?;
+    // ...
+
+    let state = Arc::new(RwLock::new(AppState {
+        hotshot_qs,
+        // additional state for other modules
+    }));
+    let mut app = App::with_state(state.clone());
+    // Register API modules.
+
+    spawn(async move {
+        let mut events = hotshot.get_event_stream(Default::default()).await.0;
+        while let Some(event) = events.next().await {
+            let mut state = state.write().await;
+            UpdateDataSource::<AppTypes>::update(&mut state.hotshot_qs, &event)
+                .await
+                .unwrap();
+            // Update other modules' states based on `event`. Use `hotshot_qs` to include
+            // database updates in the same atomic transaction as `hotshot_qs.update`.
+            let tx = state.hotshot_qs.transaction().await.unwrap();
+
+            // Commit all outstanding changes to the entire state at the same time.
+            state.hotshot_qs.commit().await.unwrap();
+        }
+    });
+
+    Ok(app)
+}

Persistent storage for data sources.

Naturally, an archival query service such as this is heavily dependent on a persistent storage +implementation. This module defines the interfaces required of this storage. Any storage layer +implementing the appropriate interfaces can be used as the storage layer when constructing a +FetchingDataSource, which can in turn be used to instantiate the +REST APIs provided by this crate.

This module also comes with a few pre-built persistence implementations:

Macro hotshot_query_service::data_source::storage::sql::include_migrations

source · 
macro_rules! include_migrations {
+    ($dir:tt) => { ... };
+}
Expand description

Embed migrations from the given directory into the current binary.

+

The macro invocation include_migrations!(path) evaluates to an expression of type impl Iterator<Item = Migration>. Each migration must be a text file which is an immediate child of +path, and there must be no non-migration files in path. The migration files must have names +of the form V${version}__${name}.sql, where version is a positive integer indicating how the +migration is to be ordered relative to other migrations, and name is a descriptive name for +the migration.

+

path should be an absolute path. It is possible to give a path relative to the root of the +invoking crate by using environment variable expansions and the CARGO_MANIFEST_DIR environment +variable.

+

As an example, this is the invocation used to load the default migrations from the +hotshot-query-service crate. The migrations are located in a directory called migrations at +the root of the crate.

+ +
let migrations: Vec<Migration> = include_migrations!("$CARGO_MANIFEST_DIR/migrations").collect();
+assert_eq!(migrations[0].version(), 10);
+assert_eq!(migrations[0].name(), "init_schema");
+

Note that a similar macro is available from Refinery: +embed_migrations. This +macro differs in that it evaluates to an iterator of migrations, making it an +expression macro, while embed_migrations is a statement macro that defines a module which +provides access to the embedded migrations only indirectly via a +Runner. The direct access to +migrations provided by include_migrations makes this macro easier to use with +Config::migrations, for combining custom migrations with default_migrations.

Expand description

The Error type, a wrapper around a dynamic error type.

+

Error works a lot like Box<dyn std::error::Error>, but with these +differences:

+
    +
  • Error requires that the error is Send, Sync, and 'static.
    • +
  • Error guarantees that a backtrace is available, even if the underlying +error type does not provide one.
    • +
  • Error is represented as a narrow pointer — exactly one word in +size instead of two.
    • +
+
+

Display representations

+

When you print an error object using “{}” or to_string(), only the outermost +underlying error or context is printed, not any of the lower level causes. +This is exactly as if you had called the Display impl of the error from +which you constructed your anyhow::Error.

+
Failed to read instrs from ./path/to/instrs.json
+
+

To print causes as well using anyhow’s default formatting of causes, use the +alternate selector “{:#}”.

+
Failed to read instrs from ./path/to/instrs.json: No such file or directory (os error 2)
+
+

The Debug format “{:?}” includes your backtrace if one was captured. Note +that this is the representation you get by default if you return an error +from fn main instead of printing it explicitly yourself.

+
Error: Failed to read instrs from ./path/to/instrs.json
+
+Caused by:
+    No such file or directory (os error 2)
+
+

and if there is a backtrace available:

+
Error: Failed to read instrs from ./path/to/instrs.json
+
+Caused by:
+    No such file or directory (os error 2)
+
+Stack backtrace:
+   0: <E as anyhow::context::ext::StdError>::ext_context
+             at /git/anyhow/src/backtrace.rs:26
+   1: core::result::Result<T,E>::map_err
+             at /git/rustc/src/libcore/result.rs:596
+   2: anyhow::context::<impl anyhow::Context<T,E> for core::result::Result<T,E>>::with_context
+             at /git/anyhow/src/context.rs:58
+   3: testing::main
+             at src/main.rs:5
+   4: std::rt::lang_start
+             at /git/rustc/src/libstd/rt.rs:61
+   5: main
+   6: __libc_start_main
+   7: _start
+
+

To see a conventional struct-style Debug representation, use “{:#?}”.

+
Error {
+    context: "Failed to read instrs from ./path/to/instrs.json",
+    source: Os {
+        code: 2,
+        kind: NotFound,
+        message: "No such file or directory",
+    },
+}
+
+

If none of the built-in representations are appropriate and you would prefer +to render the error and its cause chain yourself, it can be done something +like this:

+ +
use anyhow::{Context, Result};
+
+fn main() {
+    if let Err(err) = try_main() {
+        eprintln!("ERROR: {}", err);
+        err.chain().skip(1).for_each(|cause| eprintln!("because: {}", cause));
+        std::process::exit(1);
+    }
+}
+
+fn try_main() -> Result<()> {
+    ...
+}
+

Implementations§

source§

impl Error

source

pub fn new<E>(error: E) -> Errorwhere + E: Error + Send + Sync + 'static,

Create a new error object from any error type.

+

The error type must be threadsafe and 'static, so that the Error +will be as well.

+

If the error type does not provide a backtrace, a backtrace will be +created here to ensure that a backtrace exists.

+
source

pub fn msg<M>(message: M) -> Errorwhere + M: Display + Debug + Send + Sync + 'static,

Create a new error object from a printable error message.

+

If the argument implements std::error::Error, prefer Error::new +instead which preserves the underlying error’s cause chain and +backtrace. If the argument may or may not implement std::error::Error +now or in the future, use anyhow!(err) which handles either way +correctly.

+

Error::msg("...") is equivalent to anyhow!("...") but occasionally +convenient in places where a function is preferable over a macro, such +as iterator or stream combinators:

+ +
use anyhow::{Error, Result};
+use futures::stream::{Stream, StreamExt, TryStreamExt};
+
+async fn demo<S>(stream: S) -> Result<Vec<Output>>
+where
+    S: Stream<Item = Input>,
+{
+    stream
+        .then(ffi::do_some_work) // returns Result<Output, &str>
+        .map_err(Error::msg)
+        .try_collect()
+        .await
+}
+
source

pub fn context<C>(self, context: C) -> Errorwhere + C: Display + Send + Sync + 'static,

Wrap the error value with additional context.

+

For attaching context to a Result as it is propagated, the +Context extension trait may be more convenient than +this function.

+

The primary reason to use error.context(...) instead of +result.context(...) via the Context trait would be if the context +needs to depend on some data held by the underlying error:

+ +
use anyhow::Result;
+use std::fs::File;
+use std::path::Path;
+
+struct ParseError {
+    line: usize,
+    column: usize,
+}
+
+fn parse_impl(file: File) -> Result<T, ParseError> {
+    ...
+}
+
+pub fn parse(path: impl AsRef<Path>) -> Result<T> {
+    let file = File::open(&path)?;
+    parse_impl(file).map_err(|error| {
+        let context = format!(
+            "only the first {} lines of {} are valid",
+            error.line, path.as_ref().display(),
+        );
+        anyhow::Error::new(error).context(context)
+    })
+}
+
source

pub fn chain(&self) -> Chain<'_>

An iterator of the chain of source errors contained by this Error.

+

This iterator will visit every error in the cause chain of this error +object, beginning with the error that this error object was created +from.

+
Example
+
use anyhow::Error;
+use std::io;
+
+pub fn underlying_io_error_kind(error: &Error) -> Option<io::ErrorKind> {
+    for cause in error.chain() {
+        if let Some(io_error) = cause.downcast_ref::<io::Error>() {
+            return Some(io_error.kind());
+        }
+    }
+    None
+}
+
source

pub fn root_cause(&self) -> &(dyn Error + 'static)

The lowest level cause of this error — this error’s cause’s +cause’s cause etc.

+

The root cause is the last error in the iterator produced by +chain().

+
source

pub fn is<E>(&self) -> boolwhere + E: Display + Debug + Send + Sync + 'static,

Returns true if E is the type held by this error object.

+

For errors with context, this method returns true if E matches the +type of the context C or the type of the error on which the +context has been attached. For details about the interaction between +context and downcasting, see here.

+
source

pub fn downcast<E>(self) -> Result<E, Error>where + E: Display + Debug + Send + Sync + 'static,

Attempt to downcast the error object to a concrete type.

+
source

pub fn downcast_ref<E>(&self) -> Option<&E>where + E: Display + Debug + Send + Sync + 'static,

Downcast this error object by reference.

+
Example
+
// If the error was caused by redaction, then return a tombstone instead
+// of the content.
+match root_cause.downcast_ref::<DataStoreError>() {
+    Some(DataStoreError::Censored(_)) => Ok(Poll::Ready(REDACTED_CONTENT)),
+    None => Err(error),
+}
+
source

pub fn downcast_mut<E>(&mut self) -> Option<&mut E>where + E: Display + Debug + Send + Sync + 'static,

Downcast this error object by mutable reference.

source · 
pub struct SqlDataSource<Types>where
-    Types: NodeType,{ /* private fields */ }
Expand description

A data source for the APIs provided in this crate, backed by a remote PostgreSQL database.

-

Administration

-

This data source will automatically connect to and perform queries on a remote SQL database. -However, administration of the database, such as initialization, resetting, and backups, is -left out of the scope of this implementation, and is expected to be performed manually using -off-the-shelf DBMS adminstration tools. The one exception is migrations, which are handled -transparently by the SqlDataSource.

-

Schema

-

All the objects created and used by SqlDataSource are grouped under a schema for easy -management. By default, the schema is named hotshot, and is created the first time a -SqlDataSource is constructed. The name of the schema can be configured by setting -Config::schema.

-

Initialization

-

When creating a SqlDataSource, the caller can use Config to specify the host, user, and -database to connect to. As such, SqlDataSource is not very opinionated about how the -Postgres instance is set up. The administrator must simply ensure that there is a database -dedicated to the SqlDataSource and a user with appropriate permissions (all on SCHEMA and -all on DATABASE) over that database.

-

Here is an example of how a sufficient database could be initialized. When using the standard -postgres Docker image, these statements could be placed in -/docker-entrypoint-initdb.d/init.sql to automatically initialize the database upon startup.

-
CREATE DATABASE hotshot_query_service;
-\connect hotshot_query_service;
-CREATE USER hotshot_user WITH PASSWORD 'password';
-GRANT ALL ON SCHEMA public TO hotshot_user;
-GRANT ALL ON DATABASE hotshot_query_service TO hotshot_user WITH GRANT OPTION;
-
-

One could then connect to this database with the following Config:

- -
Config::default()
-    .host("postgres.database.hostname")
-    .database("hotshot_query_service")
-    .user("hotshot_user")
-    .password("password")
-

Resetting

-

In general, resetting the database when necessary is left up to the administrator. However, for -convenience, we do provide a reset_schema option which can be used to -wipe out existing state and create a fresh instance of the query service. This is particularly -useful for development and staging environments. This function will permanently delete all -tables associated with the schema used by this query service, but will not reset other schemas -or database.

-

Migrations

-

For the SqlDataSource to work, the database must be initialized with the appropriate schema, -and the schema must be kept up to date when deploying a new version of this software which -depends on a different schema. Both of these tasks are accomplished via migrations.

-

Each release of this software is bundled with a sequence of migration files: one migration for -each release that changed the schema, including the latest one. Replaying these SQL files -against a database with an older version of the schema, including a completely empty database, -will bring it up to date with the schema required by this version of the software. Upon creating -an instance of SqlDataSource and connecting to a database, the data source will -automatically fetch the current version from the database and, if it is old, replay the -necessary migration files.

-

Custom Migrations

-

In keeping with the philosophy of this crate, SqlDataSource is designed to be -extensible and composable. When extending the provided APIs with -new, application-specific queries, it will often be desirable to alter the schema of the -database in some way, such as adding additional columns to some of the tables or creating new -indices. When composing the provided APIs with additional API modules, it may also be desirable -to alter the schema, although the changes are more likely to be completely independent of the -schema used by this data source, such as adding entirely new tables.

-

In either case, the default schema can be modified by inserting additional migrations between -the migrations distributed with this crate. The new migrations will then automatically be -replayed as necessary when initializing a SqlDataSource. New custom migrations can be -added with each software update, to keep the custom data up to date as the default schema -changes.

-

Custom migrations can be inserted using Config::migrations. Each custom migration will be -inserted into the overall sequence of migrations in order of version number. The migrations -provided by this crate only use version numbers which are multiples of 10, so the non-multiples -can be used to insert custom migrations between the default migrations. You can also replace a -default migration completely by providing a custom migration with the same version number. This -may be useful when an earlier custom migration has altered the schema in such a way that a later -migration no longer works as-is. However, this technique is error prone and should be used only -when necessary.

-

When using custom migrations, it is the user’s responsibility to ensure that the resulting -schema is compatible with the schema expected by SqlDataSource. Adding things (tables, -columns, indices) should usually be safe. Removing, altering, or renaming things should be done -with extreme caution.

-

It is standard to store custom migrations as SQL files in a sub-directory of the crate. For ease -of release and deploymenet, such directories can be embedded into a Rust binary and parsed into -a list of Migration objects using the include_migrations macro.

-

It is also possible to take complete control over migrating the schema using -Config::no_migrations to prevent the SqlDataSource from running its own migrations. The -database administrator then becomes responsible for manually migrating the database, ensuring the -schema is up to date, and ensuring that the schema is at all times compatible with the schema -expected by the current version of this software. Nevertheless, this may be the best option when -your application-specific schema has diverged significantly from the default schema.

-

Synchronization

-

SqlDataSource implements VersionedDataSource, which means changes are not applied to the -underlying database with every operation. Instead, outstanding changes are batched and applied -all at once, atomically, whenever commit is called. Outstanding, uncommitted -changes can also be rolled back completely using revert.

-

Internally, the data source maintains an open Transaction whenever there are outstanding -changes, and commits the transaction on commit. The underlying database -transaction can be accessed directly via transaction, which makes it -possible to compose application-specific database updates atomically with updates made by the -SqlDataSource itself. This is useful for extension and -composition.

-

Extension and Composition

-

SqlDataSource is designed to be both extensible (so you can add additional state to the API -modules defined in this crate) and composable (so you can use SqlDataSource as one component -of a larger state type for an application with additional modules).

-

Extension

-

It is possible to add additional, application-specific state to SqlDataSource. If the new -state should live in memory, simply wrap the SqlDataSource in an -ExtensibleDataSource:

- -
type AppState = &'static str;
-
-let data_source: ExtensibleDataSource<SqlDataSource<AppTypes>, AppState> =
-    ExtensibleDataSource::new(SqlDataSource::connect(config).await?, "app state");
-

The ExtensibleDataSource wrapper implements all the same data -source traits as SqlDataSource, and also provides access to the AppState parameter for use -in API endpoint handlers. This can be used to implement an app-specific data source trait and -add a new API endpoint that uses this app-specific data, as described in the -extension guide.

-

If the new application-specific state should live in the SQL database itself, the implementation -is more involved, but still possible. Follow the steps for -custom migrations to modify the database schema to account for the new -data you want to store. You can then access this data through the SqlDataSource using -query to run a custom read-only SQL query or transaction -to execute a custom atomic mutation of the database. If you use -transaction, be sure to call commit when you are ready -to persist your changes.

-

You will typically use query to read custom data in API endpoint handlers and -transaction to populate custom data in your web server’s update loop.

-

Composition

-

Composing SqlDataSource with other module states is fairly simple – just -create an aggregate struct containing both SqlDataSource and your additional module -states, as described in the composition guide. If the additional modules -have data that should live in the same database as the SqlDataSource data, you can follow -the steps in custom migrations to accomodate this. When modifying that -data, you can use transaction to atomically synchronize updates to the -other modules’ data with updates to the SqlDataSource. If the additional data is completely -independent of HotShot query service data and does not need to be synchronized, you can also -connect to the database directly to make updates.

-

In the following example, we compose HotShot query service modules with other application- -specific modules, synchronizing updates using transaction.

- -
struct AppState {
-    hotshot_qs: SqlDataSource<AppTypes>,
-    // additional state for other modules
-}
-
-async fn init_server(
-    config: Config,
-    mut hotshot: SystemContextHandle<AppTypes, AppNodeImpl>,
-) -> Result<App<Arc<RwLock<AppState>>, Error>, Error> {
-    let mut hotshot_qs = SqlDataSource::connect(config).await.map_err(Error::internal)?;
-    // Initialize storage for other modules, using `hotshot_qs` to access the database.
-    let tx = hotshot_qs.transaction().await.map_err(Error::internal)?;
-    // ...
-
-    let state = Arc::new(RwLock::new(AppState {
-        hotshot_qs,
-        // additional state for other modules
-    }));
-    let mut app = App::with_state(state.clone());
-    // Register API modules.
-
-    spawn(async move {
-        let mut events = hotshot.get_event_stream(Default::default()).await.0;
-        while let Some(event) = events.next().await {
-            let mut state = state.write().await;
-            UpdateDataSource::<AppTypes>::update(&mut state.hotshot_qs, &event)
-                .await
-                .unwrap();
-            // Update other modules' states based on `event`. Use `hotshot_qs` to include
-            // database updates in the same atomic transaction as `hotshot_qs.update`.
-            let tx = state.hotshot_qs.transaction().await.unwrap();
-
-            // Commit all outstanding changes to the entire state at the same time.
-            state.hotshot_qs.commit().await.unwrap();
-        }
-    });
-
-    Ok(app)

Persistent storage for a HotShot blockchain.

+

This trait defines the interface which must be provided by the storage layer in order to +implement an availability data source. It is very similar to +AvailabilityDataSource with every occurrence of +Fetch replaced by QueryResult. This is not a coincidence. +The purpose of the storage layer is to provide all of the functionality of the data source +layer, but independent of an external fetcher for missing data. Thus, when the storage layer +encounters missing, corrupt, or inaccessible data, it simply gives up and replaces the missing +data with Err, rather than creating an asynchronous fetch request to retrieve the missing +data.

+

Rust gives us ways to abstract and deduplicate these two similar APIs, but they do not lead to a +better interface.

pub struct FileSystemDataSource<Types: NodeType>where
-    Payload<Types>: QueryablePayload,{ /* private fields */ }
Expand description

A data source for the APIs provided in this crate, backed by the local file system.

-

Synchronization and atomicity of persisted data structures are provided via [atomic_store]. -The methods commit, revert, and -skip_version of this type can be used to control synchronization in the -underlying [AtomicStore].

-

Extension and Composition

-

FileSystemDataSource is designed to be both extensible (so you can add additional state to -the API modules defined in this crate) and composable (so you can use FileSystemDataSource -as one component of a larger state type for an application with additional modules).

-

Extension

-

Adding additional, application-specific state to FileSystemDataSource is possible by -wrapping it in ExtensibleDataSource:

- -
type AppState = &'static str;
-
-let data_source: ExtensibleDataSource<FileSystemDataSource<AppTypes>, AppState> =
-    ExtensibleDataSource::new(FileSystemDataSource::create(storage_path).await?, "app state");
-

The ExtensibleDataSource wrapper implements all the same data -source traits as FileSystemDataSource, and also provides access to the AppState parameter -for use in API endpoint handlers. This can be used to implement an app-specific data source -trait and add a new API endpoint that uses this app-specific data, as described in the -extension guide.

-

Composition

-

Composing FileSystemDataSource with other module states is in principle simple – just -create an aggregate struct containing both FileSystemDataSource and your additional module -states. A complication arises from how persistent storage is managed: if other modules have -their own persistent state, should the storage of FileSystemDataSource and the other modules -be completely independent, or synchronized under the control of a single [AtomicStore]? -FileSystemDataSource supports both patterns: when you create it with -create or open, it will open its own [AtomicStore] and -manage the synchronization of its own storage, independent of any other persistent data it might -be composed with. But when you create it with create_with_store or -open_with_store, you may ask it to register its persistent data -structures with an existing [AtomicStoreLoader]. If you register other modules’ persistent -data structures with the same loader, you can create one [AtomicStore] that synchronizes all -the persistent data. Note, though, that when you choose to use -create_with_store or open_with_store, -you become responsible for ensuring that calls to [AtomicStore::commit_version] alternate with -calls to FileSystemDataSource::commit or FileSystemDataSource::revert.

-

In the following example, we compose HotShot query service modules with other application- -specific modules, using a single top-level [AtomicStore] to synchronize all persistent -storage.

- -
struct AppState {
-    // Top-level storage coordinator
-    store: AtomicStore,
-    hotshot_qs: FileSystemDataSource<AppTypes>,
-    // additional state for other modules
-}
-
-async fn init_server(
-    storage_path: &Path,
-    mut hotshot: SystemContextHandle<AppTypes, AppNodeImpl>,
-) -> Result<App<Arc<RwLock<AppState>>, Error>, Error> {
-    let mut loader = AtomicStoreLoader::create(storage_path, "my_app") // or `open`
-        .map_err(Error::internal)?;
-    let hotshot_qs = FileSystemDataSource::create_with_store(&mut loader)
-        .await
-        .map_err(Error::internal)?;
-    // Initialize storage for other modules using the same loader.
-
-    let store = AtomicStore::open(loader).map_err(Error::internal)?;
-    let state = Arc::new(RwLock::new(AppState {
-        store,
-        hotshot_qs,
-        // additional state for other modules
-    }));
-    let mut app = App::with_state(state.clone());
-    // Register API modules.
-
-    spawn(async move {
-        let mut events = hotshot.get_event_stream(Default::default()).await.0;
-        while let Some(event) = events.next().await {
-            let mut state = state.write().await;
-            state.hotshot_qs.update(&event).await.unwrap();
-            // Update other modules' states based on `event`.

source · 
pub struct FetchingDataSource<Types, S, P>where
+    Types: NodeType,{ /* private fields */ }
Expand description

The most basic kind of data source.

+

A data source is constructed modularly by combining a storage implementation +with a fetcher. The former allows the query service to store the data it has +persistently in an easily accessible storage medium, such as the local file system or a +database. This allows it to answer queries efficiently and to maintain its state across +restarts. The latter allows the query service to fetch data that is missing from its storage +from an external data availability provider, such as the Tiramisu DA network or another instance +of the query service.

+

These two components of a data source are combined in FetchingDataSource, which is the +lowest level kind of data source available. It simply uses the storage implementation to fetch +data when available, and fills in everything else using the fetcher. Various kinds of data +sources can be constructed out of FetchingDataSource by changing the storage and fetcher +implementations used, and more complex data sources can be built on top using data source +combinators.

    Expand description

    A data source for the APIs provided in this crate, backed by the local file system.

    +

    Synchronization and atomicity of persisted data structures are provided via [atomic_store]. +The methods commit, +revert, and skip_version of this +type can be used to control synchronization in the underlying +AtomicStore.

    +

    Extension and Composition

    +

    FileSystemDataSource is designed to be both extensible (so you can add additional state to +the API modules defined in this crate) and composable (so you can use FileSystemDataSource +as one component of a larger state type for an application with additional modules).

    +

    Extension

    +

    Adding additional, application-specific state to FileSystemDataSource is possible by +wrapping it in ExtensibleDataSource:

    + +
    type AppState = &'static str;
+
+let data_source: ExtensibleDataSource<FileSystemDataSource<AppTypes>, AppState> =
+    ExtensibleDataSource::new(FileSystemDataSource::create(storage_path).await?, "app state");
    +

    The ExtensibleDataSource wrapper implements all the same data +source traits as FileSystemDataSource, and also provides access to the AppState parameter +for use in API endpoint handlers. This can be used to implement an app-specific data source +trait and add a new API endpoint that uses this app-specific data, as described in the +extension guide.

    +

    Composition

    +

    Composing FileSystemDataSource with other module states is in principle simple – just +create an aggregate struct containing both FileSystemDataSource and your additional module +states. A complication arises from how persistent storage is managed: if other modules have +their own persistent state, should the storage of FileSystemDataSource and the other modules +be completely independent, or synchronized under the control of a single +AtomicStore? FileSystemDataSource supports both patterns: +when you create it with create or open, it will open its own +AtomicStore and manage the synchronization of its own storage, +independent of any other persistent data it might be composed with. But when you create it with +create_with_store or open_with_store, +you may ask it to register its persistent data structures with an existing +[AtomicStoreLoader]. If you register other modules’ persistent data structures with the same +loader, you can create one AtomicStore that synchronizes all the +persistent data. Note, though, that when you choose to use +create_with_store or open_with_store, +you become responsible for ensuring that calls to +AtomicStore::commit_version alternate with calls +to commit or +revert.

    +

    In the following example, we compose HotShot query service modules with other application- +specific modules, using a single top-level AtomicStore to +synchronize all persistent storage.

    + +
    struct AppState {
+    // Top-level storage coordinator
+    store: AtomicStore,
+    hotshot_qs: FileSystemDataSource<AppTypes>,
+    // additional state for other modules
+}
+
+async fn init_server(
+    storage_path: &Path,
+    mut hotshot: SystemContextHandle<AppTypes, AppNodeImpl>,
+) -> Result<App<Arc<RwLock<AppState>>, Error>, Error> {
+    let mut loader = AtomicStoreLoader::create(storage_path, "my_app") // or `open`
+        .map_err(Error::internal)?;
+    let hotshot_qs = FileSystemDataSource::create_with_store(&mut loader)
+        .await
+        .map_err(Error::internal)?;
+    // Initialize storage for other modules using the same loader.
+
+    let store = AtomicStore::open(loader).map_err(Error::internal)?;
+    let state = Arc::new(RwLock::new(AppState {
+        store,
+        hotshot_qs,
+        // additional state for other modules
+    }));
+    let mut app = App::with_state(state.clone());
+    // Register API modules.
+
+    spawn(async move {
+        let mut events = hotshot.get_event_stream(Default::default()).await.0;
+        while let Some(event) = events.next().await {
+            let mut state = state.write().await;
+            state.hotshot_qs.update(&event).await.unwrap();
+            // Update other modules' states based on `event`.
+
+            state.hotshot_qs.commit().await.unwrap();
+            // Commit or skip versions for other modules' storage.
+            state.store.commit_version().unwrap();
+        }
+    });
+
+    Ok(app)
+}

    A node’s view of a HotShot chain
    
+
    The node API provides a subjective view of the HotShot blockchain, from the perspective of
+one particular node. It provides access to information that the
+availability API does not, because this information depends on the
+perspective of the node observing it, and may be subject to eventual consistency. For example,
+/node/block-height and /node/proposals/:proposer_id/count may both return smaller counts
+than expected, if the node being queried is not fully synced with the entire history of the
+chain. However, the node will eventually sync and return the expected counts.

    Queries for node-specific state and uncommitted data.
    
+
    Unlike the availability and node APIs, which deal only
+with committed data (albeit with different consistency properties), the status API offers a
+glimpse into internal consensus state and uncommitted data. Here you can find low-level
+information about a particular node, such as consensus and networking metrics. You can also find
+information about pending blocks and transactions in the mempool.
    
+
    The status API is intended to be a lightweight way to inspect the activities and health of a
+consensus node. It is the only API that can be run without any persistent storage, and its
+memory overhead is also very low. As a consequence, it only serves two types of data:
    
+
      
+
    • snapshots of the state right now, with no way to query historical snapshots
      • 
+
    • summary statistics
      •

+//! Queries for HotShot chain state.
+//!
+//! The availability API provides an objective view of the HotShot blockchain. It provides access
+//! only to normative data: that is, data which is agreed upon by all honest consensus nodes and
+//! which is immutable. This means access to core consensus data structures including leaves,
+//! blocks, and headers, where each query is pure and idempotent. This also means that it is
+//! possible for a client to verify all of the information provided by this API, by running a
+//! HotShot light client and downloading the appropriate evidence with each query.
+//!
+//! This API does not provide any queries which represent only the _current_ state of the chain or
+//! may change over time, and it does not provide information for which there is not (yet) agreement
+//! of a supermajority of consensus nodes. For information about the current dynamic state of
+//! consensus and uncommitted state, try the [status](crate::status) API. For information about the
+//! chain which is tabulated by this specific node and not subject to full consensus agreement, try
+//! the [node](crate::node) API.

-#[async_trait]
+/// An interface for querying a HotShot blockchain.
+///
+/// This interface provides expressive queries over all the data which is made available by HotShot
+/// consensus. The data exposed by this interface consists entirely of _normative_ data: data which
+/// every correct HotShot node or light client will agree on, and which is guaranteed by consensus
+/// to be immutable. This immutability has an interesting consequence: all of the methods exposed by
+/// this trait are _pure_: given equivalent inputs, the same method will always return equivalent
+/// outputs[^1].
+///
+/// This purity property has a further consequence: none of the methods defined here can fail! Even
+/// if you query for a block at a position past the end of the current chain -- a block which does
+/// not exist yet -- the query will not fail. It will return an in-progress [`Fetch`] which, when it
+/// finally does resolve, resolves to the unique block at that position in the chain. All subsequent
+/// queries for the same position will eventually resolve to the same block.
+///
+/// In other words, the abstraction is that of an infinitely long chain which exists statically, in
+/// its entirety, at all times. In reality, of course, this chain is being produced incrementally
+/// and has a finite length at any given time. But all this means is that some queries may take a
+/// long time to resolve while others may resolve immediately.
+///
+/// [^1]: The data returned by these methods are wrapped in [`Fetch`], which does not implement
+///       [`PartialEq]`. So to speak of equivalent outputs, we need to define an equivalence
+///       relation on [`Fetch<T>`]. The relation we will use is defined when `T: PartialEq`, and
+///       defines two fetches `f1` and `f2` as equivalent when `f1.await == f2.await`. That is,
+///       depending on when you call a certain method, you may or may not get a response
+///       immediately. But whenever you do get the data you requested, it is unique for that
+///       combination of inputs.

-//! Async channel with message buffering.

-//! A buffered channel is an async, in-memory broadcast channel which buffers messages before
-//! delivering them. Unlike a typical channel, sending a message only buffers the message in the
-//! sender. Receivers are not notified immediately. Only when [`flush`](BufferedChannel::flush) is
-//! called are all buffered messages delivered to receivers. [`clear`](BufferedChannel::clear) can
-//! also be used to drop all buffered messages without ever notifying receivers.

+/// A data source is constructed modularly by combining a [storage](super::storage) implementation

+/// persistently in an easily accessible storage medium, such as the local file system or a
+/// database. This allows it to answer queries efficiently and to maintain its state across
+/// restarts. The latter allows the query service to fetch data that is missing from its storage
+/// from an external data availability provider, such as the Tiramisu DA network or another instance
+/// of the query service.
+///
+/// These two components of a data source are combined in [`FetchingDataSource`], which is the
+/// lowest level kind of data source available. It simply uses the storage implementation to fetch
+/// data when available, and fills in everything else using the fetcher. Various kinds of data
+/// sources can be constructed out of [`FetchingDataSource`] by changing the storage and fetcher
+/// implementations used, and more complex data sources can be built on top using data source

+//! Multi-producer, multi-consumer oneshot notification channel
+//!
+//! [`Notifier`] is an asynchronous, multi-producer, multi-consumer, oneshot channel satisfying
+//! three additional requirements:
+//! 1. Dropped receivers do not consume resources.
+//! 2. Messages are not copied for receivers who don't want them.
+//! 3. Minimal resource contention for concurrent subscriptions.
+//!
+//! ## Dropped receivers do not consume resources
+//!
+//! This requirement is a direct prerequisite of the broader requirement that passive requests for
+//! resources do not consume resources. This is important because in general, passive requests may
+//! be for resources that are not guaranteed to exist, and thus may never terminate. Just like we
+//! avoid spawning a task for passive requests, since it may never complete, we need receivers for
+//! passive requests not to persist beyond the lifetime of the requst, or they may never be closed.
+//!
+//! This requirement is implemented via garbage collection: each time a message is sent, resources
+//! belonging to dropped receivers are cleaned up. Thus, strictly speaking, dropped receivers do
+//! consume resources, but only briefly. There is no need to keep them around until the desired
+//! message is delivered, for example.
+//!
+//! ## Messages are not copied for receivers who don't want them.
+//!
+//! The second requirement simplifies the higher level fetching logic by allowing us to maintain a
+//! single channel for all notifications about a particular resource type, rather than separate
+//! channels for each specific request. Since messages are not copied for all subscribers, but only
+//! for the subscribers interested in a particular message, this simplification becomes nearly
+//! cost-free.
+//!
+//! This requirement is implemented by attaching a predicate to each subscription, which takes a
+//! message by reference. The predicate is checked on the sending side, and the message is only
+//! copied to the subscription if the predicate is satisfied.
+//!
+//! ## Minimal resource contention for concurrent subscriptions.
+//!
+//! This is important because subscriptions are requested in response to read-only client requests,
+//! which are supposed to run in parallel as much as possible. By contrast, notifications are
+//! ususally send from internal server tasks (e.g. the background task that updates the data source
+//! when new blocks are committed). It is less of a problem if these internal tasks contend with
+//! each other, because they are not directly blocking responses to clients, and we have more
+//! control over how and when they acquire shared resources.
+//!
+//! This requirement also empowers us to create a simpler design for the high-level fetching logic.
+//! Specifically, we can reuse the same code for fetching individual resources as we use for
+//! long-lived subscription streams (e.g. `subscribe_blocks` is a thin wrapper around
+//! `get_block_range`). We do not have to worry about adding complex logic to reuse notification
+//! subscriptions for long-lived streams, because subscribing anew for each entry in the stream has
+//! low overhead in terms of contention over shared resources -- the dominant caused in any
+//! concurrent channel, after data copying (see above).
+//!
+//! This further lets us simplify the interface of this channel a bit: since all notifications are
+//! oneshot, consumers deal with futures rather than streams.
+//!
+//! This requirement is satisfied by maintaining the list of subscribers to a [`Notifier`] in a way
+//! that moves most resource contention to message senders, rather than receivers. We make the
+//! assumption that there is less concurrency among senders. In the common case, there is just one
+//! sender: the task monitoring HotShot for new blocks. Occasionally, there may be other tasks
+//! spawned to fetch missing resources and send them through the [`Notifier`], but these should be
+//! relatively few and rare.

+    //    moving cost from receivers to senders is always good.
+    // 2. This channel is intended to be highly concurrent, and `active` is a shared resource that

+    //    subscribers list, but new subscriptions do not. Again, since there are often more
+    //    receivers than senders, this can reduce contention significantly.

-// This needs to be reexported so that we can reference it by absolute path relative to this crate

-/// Embed migrations from the given directory into the current binary.
-///
-/// The macro invocation `include_migrations!(path)` evaluates to an expression of type `impl
-/// Iterator<Item = Migration>`. Each migration must be a text file which is an immediate child of
-/// `path`, and there must be no non-migration files in `path`. The migration files must have names
-/// of the form `V${version}__${name}.sql`, where `version` is a positive integer indicating how the
-/// migration is to be ordered relative to other migrations, and `name` is a descriptive name for
-/// the migration.
-///
-/// `path` should be an absolute path. It is possible to give a path relative to the root of the
-/// invoking crate by using environment variable expansions and the `CARGO_MANIFEST_DIR` environment
-/// variable.
-///
-/// As an example, this is the invocation used to load the default migrations from the
-/// `hotshot-query-service` crate. The migrations are located in a directory called `migrations` at
-/// the root of the crate.
-///
-/// ```
-/// # use hotshot_query_service::data_source::sql::{include_migrations, Migration};
-/// let migrations: Vec<Migration> = include_migrations!("$CARGO_MANIFEST_DIR/migrations").collect();
-/// assert_eq!(migrations[0].version(), 10);
-/// assert_eq!(migrations[0].name(), "init_schema");
-/// ```
-///
-/// Note that a similar macro is available from Refinery:
-/// [embed_migrations](https://docs.rs/refinery/0.8.11/refinery/macro.embed_migrations.html). This
-/// macro differs in that it evaluates to an iterator of [migrations](Migration), making it an
-/// expression macro, while `embed_migrations` is a statement macro that defines a module which
-/// provides access to the embedded migrations only indirectly via a
-/// [`Runner`](https://docs.rs/refinery/0.8.11/refinery/struct.Runner.html). The direct access to
-/// migrations provided by [`include_migrations`] makes this macro easier to use with
-/// [`Config::migrations`], for combining custom migrations with [`default_migrations`].

+//! Persistent storage for data sources.
+//!
+//! Naturally, an archival query service such as this is heavily dependent on a persistent storage
+//! implementation. This module defines the interfaces required of this storage. Any storage layer
+//! implementing the appropriate interfaces can be used as the storage layer when constructing a
+//! [`FetchingDataSource`](super::FetchingDataSource), which can in turn be used to instantiate the
+//! REST APIs provided by this crate.
+//!
+//! This module also comes with a few pre-built persistence implementations:
+//! * [`SqlStorage`]
+//! * [`FileSystemStorage`]
+//!

+/// Persistent storage for a HotShot blockchain.
+///
+/// This trait defines the interface which must be provided by the storage layer in order to
+/// implement an availability data source. It is very similar to
+/// [`AvailabilityDataSource`](crate::availability::AvailabilityDataSource) with every occurrence of
+/// [`Fetch`](crate::availability::Fetch) replaced by [`QueryResult`]. This is not a coincidence.
+/// The purpose of the storage layer is to provide all of the functionality of the data source
+/// layer, but independent of an external fetcher for missing data. Thus, when the storage layer
+/// encounters missing, corrupt, or inaccessible data, it simply gives up and replaces the missing
+/// data with [`Err`], rather than creating an asynchronous fetch request to retrieve the missing
+/// data.
+///
+/// Rust gives us ways to abstract and deduplicate these two similar APIs, but they do not lead to a
+/// better interface.

+/// The macro invocation `include_migrations!(path)` evaluates to an expression of type `impl
+/// Iterator<Item = Migration>`. Each migration must be a text file which is an immediate child of
+/// `path`, and there must be no non-migration files in `path`. The migration files must have names
+/// of the form `V${version}__${name}.sql`, where `version` is a positive integer indicating how the
+/// migration is to be ordered relative to other migrations, and `name` is a descriptive name for
+/// the migration.
+///
+/// `path` should be an absolute path. It is possible to give a path relative to the root of the
+/// invoking crate by using environment variable expansions and the `CARGO_MANIFEST_DIR` environment
+/// variable.
+///
+/// As an example, this is the invocation used to load the default migrations from the
+/// `hotshot-query-service` crate. The migrations are located in a directory called `migrations` at
+/// the root of the crate.
+///
+/// ```
+/// # use hotshot_query_service::data_source::sql::{include_migrations, Migration};
+/// let migrations: Vec<Migration> = include_migrations!("$CARGO_MANIFEST_DIR/migrations").collect();
+/// assert_eq!(migrations[0].version(), 10);
+/// assert_eq!(migrations[0].name(), "init_schema");
+/// ```
+///
+/// Note that a similar macro is available from Refinery:
+/// [embed_migrations](https://docs.rs/refinery/0.8.11/refinery/macro.embed_migrations.html). This
+/// macro differs in that it evaluates to an iterator of [migrations](Migration), making it an
+/// expression macro, while `embed_migrations` is a statement macro that defines a module which
+/// provides access to the embedded migrations only indirectly via a
+/// [`Runner`](https://docs.rs/refinery/0.8.11/refinery/struct.Runner.html). The direct access to
+/// migrations provided by [`include_migrations`] makes this macro easier to use with
+/// [`Config::migrations`], for combining custom migrations with [`default_migrations`].

+//! A node's view of a HotShot chain
+//!
+//! The node API provides a subjective view of the HotShot blockchain, from the perspective of
+//! one particular node. It provides access to information that the
+//! [availability](crate::availability) API does not, because this information depends on the
+//! perspective of the node observing it, and may be subject to eventual consistency. For example,
+//! `/node/block-height` and `/node/proposals/:proposer_id/count` may both return smaller counts
+//! than expected, if the node being queried is not fully synced with the entire history of the
+//! chain. However, the node will _eventually_ sync and return the expected counts.

+//! Queries for node-specific state and uncommitted data.
+//!
+//! Unlike the [availability](crate::availability) and [node](crate::node) APIs, which deal only
+//! with committed data (albeit with different consistency properties), the status API offers a
+//! glimpse into internal consensus state and uncommitted data. Here you can find low-level
+//! information about a particular node, such as consensus and networking metrics. You can also find
+//! information about pending blocks and transactions in the mempool.
+//!
+//! The status API is intended to be a lightweight way to inspect the activities and health of a
+//! consensus node. It is the only API that can be run without any persistent storage, and its
+//! memory overhead is also very low. As a consequence, it only serves two types of data:
+//! * snapshots of the state right now, with no way to query historical snapshots
+//! * summary statistics

    Because this function may panic, its use is generally discouraged.\nInstead, prefer to use pattern matching and handle the Err\ncase explicitly, or call unwrap_or, unwrap_or_else, or\nunwrap_or_default.

    \n
    Panics

    source§

    fn from_iter<I>(iter: I) -> Result<V, E>where\n I: IntoIterator<Item = Result<A, E>>,

    Takes each element in the Iterator: if it is an Err, no further\nelements are taken, and the Err is returned. Should no Err occur, a\ncontainer with the values of each Result is returned.

    \n

    Here is an example which increments every integer in a vector,\nchecking for overflow:

    \n\n
    let v = vec![1, 2];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_add(1).ok_or("Overflow!")\n).collect();\nassert_eq!(res, Ok(vec![2, 3]));
    \n

    Here is another example that tries to subtract one from another list\nof integers, this time checking for underflow:

    \n\n
    let v = vec![1, 2, 0];\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32|\n    x.checked_sub(1).ok_or("Underflow!")\n).collect();\nassert_eq!(res, Err("Underflow!"));
    \n

    Here is a variation on the previous example, showing that no\nfurther elements are taken from iter after the first Err.

    \n\n
    let v = vec![3, 2, 1, 10];\nlet mut shared = 0;\nlet res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| {\n    shared += x;\n    x.checked_sub(2).ok_or("Underflow!")\n}).collect();\nassert_eq!(res, Err("Underflow!"));\nassert_eq!(shared, 6);
    \n

    Since the third element caused an underflow, no further elements were taken,\nso the final value of shared is 6 (= 3 + 2 + 1), not 16.

    Returns a mutable iterator over the possibly contained value.

    \n

    The iterator yields one value if the result is Result::Ok, otherwise none.

    \n
    Examples
    \n
    let mut x: Result<u32, &str> = Ok(7);\nmatch x.iter_mut().next() {\n    Some(v) => *v = 40,\n    None => {},\n}\nassert_eq!(x, Ok(40));\n\nlet mut x: Result<u32, &str> = Err("nothing!");\nassert_eq!(x.iter_mut().next(), None);

    pub fn expect(self, msg: &str) -> Twhere\n E: Debug,

    Returns the contained Ok value, consuming the self value.

    \n

    Because this function may panic, its use is generally discouraged.\nInstead, prefer to use pattern matching and handle the Err\ncase explicitly, or call unwrap_or, unwrap_or_else, or\nunwrap_or_default.

    \n
    Panics
    \n

    Panics if the value is an Err, with a panic message including the\npassed message, and the content of the Err.

    \n
    Examples
    \n
    ⓘ
    let x: Result<u32, &str> = Err("emergency failure");\nx.expect("Testing expect"); // panics with `Testing expect: emergency failure`
    \n
    Recommended Message Style
    \n

    We recommend that expect messages are used to describe the reason you\nexpect the Result should be Ok.

    \n\n
    ⓘ
    let path = std::env::var("IMPORTANT_PATH")\n    .expect("env variable `IMPORTANT_PATH` should be set by `wrapper_script.sh`");
    \n

    Hint: If you’re having trouble remembering how to phrase expect\nerror messages remember to focus on the word “should” as in “env\nvariable should be set by blah” or “the given binary should be available\nand executable by the current user”.

    \n

    For more detail on expect message styles and the reasoning behind our recommendation please\nrefer to the section on “Common Message\nStyles” in the\nstd::error module docs.

    Panics
    \n

    Panics if the value is an Err, with a panic message provided by the\nErr’s value.

    \n
    Examples

    Basic usage:

    \n\n
    let x: Result<u32, &str> = Ok(2);\nassert_eq!(x.unwrap(), 2);

    \n
    Examples
    \n

    Converts a string to an integer, turning poorly-formed strings\ninto 0 (the default value for integers). parse converts\na string to any other type that implements FromStr, returning an\nErr on error.

    🔬This is a nightly-only experimental API. (unwrap_infallible)

    Returns the contained Ok value, but never panics.

    \n

    Unlike unwrap, this method is known to never panic on the\nresult types it is implemented for. Therefore, it can be used\ninstead of unwrap as a maintainability safeguard that will fail\nto compile if the error type of the Result is later changed\nto an error that can actually occur.

    Takes each element in the Iterator: if it is an Err, no further\nelements are taken, and the Err is returned. Should no Err occur, a\ncontainer with the values of each Result is returned.

    Here is an example which increments every integer in a vector,\nchecking for overflow:

    Here is another example that tries to subtract one from another list\nof integers, this time checking for underflow:
