v0.7.0
b92b6de

PROST! is a Protocol Buffers implementation for the Rust Language. prost generates simple, idiomatic Rust code from proto2 and proto3 files.

prost 0.7.0 includes breaking changes:

  • The minimum-supported Rust version (MSRV) is now 1.46.0.
  • The bytes public dependency version is now 1.0.
  • The bundled protoc version is now 3.14.0.

As well as many new (non-breaking) features and improvements:

  • @hockeybuggy added support for deprecated field annotations.
  • @garbageslam and @dflemstr added no_std support.
  • @joseph-wakeling-frequenz fixed a bug in Timestamp <-> SystemTime conversions.
  • @rolftimmermans added support for generating Rust bytes::Bytes fields from protobuf bytes fields. When deserializing from a Bytes instance, this enables zero-copy deserialization for bytes fields!
  • @olix0r bumped the bytes dependency to 0.6, which included most of the heavy lifting for the subsequent move to bytes 1.0.
  • @danburkert added support for the experimental proto3 optional field presence feature.

and numerous smaller fixes. Many thanks to the generous contributors who have helped out since 0.6.1:
