v0.1007.0

v0.1007.0

Breaking changes

• Tuple typed structs (with anonymous fields accessed like value.0) now start
  their field numbering from zero by default, matching the names of the fields.
• Renamed the .reader() method on ReverseBuffer to .buf_reader() so it no
  longer conflicts with the bytes::Buf method.

New features

• Added support for encoding usize and isize pointer-sized integers. They
  will still have different supported maximums on platforms with different sized
  values, but this still has completely reasonable failure modes.
• Added support for deriving Message for enum types, which is implemented in
  terms of Oneof. The message implementations encode and decode exactly like a
  message which contains only that oneof; see the readme for more details.
• Changed the Value type in bilrost-types to be a message-via-oneof in this
  way, making it much nicer to use without changing its meaning.
• Added a .slices() method to ReverseBuffer and ReverseBufferReader which
  iterates its slices, useful for sending to write_vectored.

Fixes

• Fixed some incorrect tests, including coverage of third-party inline vecs and
  packed/unpacked fixed-size arrays.

Cleanups

• Cleaned up and re-added fuzzers! Fuzzers are available via both libfuzzer
  and afl; see FUZZING.md for usage details. These fuzzers
  would have caught the bug fixed in 0.1006.1 :)
• Deduplicated and somewhat improved codegen for oneofs. All four kinds of oneof
  decoder function are now generated by the same code, which is a huge
  improvement over four independent generators.
• Added tests for detailed errors attribution of decoding errors to the specific
  field that caused the problem.
