 # :simple-rust: Rust
 <!-- markdownlint-enable single-h1 -->
 
-[TODO](https://github.com/input-output-hk/catalyst-ci/issues/78)
+## Introduction
+
+<!-- markdownlint-disable max-one-sentence-per-line -->
+!!! Tip
+    If you're just looking for a complete example,
+    [click here](https://github.com/input-output-hk/catalyst-ci/blob/master/examples/rust/Earthfile).
+    This guide will provide detailed instructions for how the example was built.
+<!-- markdownlint-enable max-one-sentence-per-line -->
+
+This guide will get you started with using the Catalyst CI to work with Rust based projects.
+
+To begin, clone the Catalyst CI repository:
+
+```bash
+git clone https://github.com/input-output-hk/catalyst-ci.git
+```
+
+Navigate to `examples/rust` to find a basic Rust project, with the `Earthfile` in it.
+This is the `Earthfile` we will be building in this guide.
+You can choose to either delete the file and start from scratch,
+or read the guide and follow along in the file.

+        BUILD --platform=linux/arm64 +build-hosted
+    ELSE
+        BUILD --platform=linux/amd64 +build-hosted
+    END
+```
+
+After successful performing checks of the Rust project we can finally build artifacts.
+As it was discussed in the previous section, actual job is done with `build-hosted` target,
+other targets needs to configure different platform running options.
+So we will focus on `build-hosted` target.
+Obviously it inherits `builder` target environment and than performs build of the binary.
+Important to note that in this particular example we are dealing with the executable Rust project,
+so it produces binary as a final artifact.
+Another case of the building Rust library we will consider later.
+Actual build process is done with `+BUILD` UDC target.
+Under this build process we perform different steps of compiling and validating of our Rust project,
+here is the list of steps (look at `./earthly/rust/scripts/std_build.sh`):
+
+1. `cargo build` - Building all code in the workspace.
+2. `cargo lint` ([cargo alias](https://doc.rust-lang.org/cargo/reference/config.html#alias),
+look at `./earthly/rust/stdcfgs/config.toml`)
+- Checking all Clippy Lints in the workspace.
+3. `cargo docs` ([cargo alias](https://doc.rust-lang.org/cargo/reference/config.html#alias),
+look at `./earthly/rust/stdcfgs/config.toml`)
+- Checking Documentation can be generated OK.
+4. `cargo testci` ([cargo alias](https://doc.rust-lang.org/cargo/reference/config.html#alias),
+look at `./earthly/rust/stdcfgs/config.toml`)
+- Checking Self contained Unit tests all pass.
+5. `cargo testdocs` ([cargo alias](https://doc.rust-lang.org/cargo/reference/config.html#alias),
+look at `./earthly/rust/stdcfgs/config.toml`)
+- Checking Documentation tests all pass.
+6. `cargo bench` - Checking Benchmarks all run to completion.
+
+Next steps is mandatory if you are going to produce a binary as an artifact,
+for Rust libraries the are not mandatory and could be omitted.
+The `+SMOKE_TEST` UDC target checks that produced binary with the specified name (`--bin` argument)
+is executable, isn't a busted mess.
+
+Final step is to provide desired artifacts: docs and binary.
+
+### Test
+
+As you already mentioned that running of unit tests is done during the `build` process,
+but if you need some integration tests pls follow how it is done for [PostgreSQL builder](./postgresql.md),
+Rust will have the same approach.
+
+### Release and publish
+
+To prepare a release artifact and publish it to some external container registries
+please follow this [guide](./../../onboarding/index.md).
+It is pretty strait forward for this builder process,
+because as a part of `+build` target we already creating a docker image.
+
+## Conclusion
+
+You can see the final `Earthfile` [here](https://github.com/input-output-hk/catalyst-ci/blob/master/examples/rust/Earthfile)
+and any other files in the same directory.
+We have learnt how to maintain and setup Rust project, as you can see it is pretty simple.

+
+This repo defines common python targets and UDCs for use with python.

+#### Invocation
+
+In an `Earthfile` in your source repository add:
+
+```Earthfile
+example_python_target:
+    FROM python:3.11-bullseye
+    DO github.com/input-output-hk/catalyst-ci:v1.2.0/earthly/python+POETRY_SETUP

+
+You may also pass optional arguments:
+
+* `extra_files`: Defining extra files into the `/poetry` directory in the container.
+* `opts`: Options to the `poetry install` command.
+
+These arguments are optional and neither is required to be set.
+
+The directory that contains the Earthfile that invokes this UDC MUST have:
+
+* `pyproject.toml` : Definitions of the project to be installed with Poetry.
+* `poetry.lock` : Dependency lock file.
+  Up-to-date by running:
+  * `poetry lock --no-update` : Update lock file, but do not update dependencies; or

 The fist step of the `builder` target is to prepare a Rust environment via `+rust-base` target.
-Next step is to copy source code of the project with the help of `+CP_SRC` UDC target.

 Note that you need to copy only needed files for Rust build process,

-The `+CP_SRC` command has only argument `src` where you can provide files, directories separated by comma,

 And finally finalize the build with `+SETUP` UDC target.
 The `+SETUP` UDC target requires `rust-toolchain.toml` file,
 with the specified `channel` option in it.
