Release v0.4.0 · tokio-rs/prost

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

prost 0.4.0 contains new features, bug-fixes, and one breaking change since
0.3.0:

@briansmith cleaned up the project dependencies and build scripts, resulting
in faster and more robust builds for all prost users.
@kestred added tag inference on fields in types which derive Message.
Tag inference reduces the number annotations necessary when manually writing
message structs.
@warrenfalk added logic to strip the enum name from enum
variants which include the enum name as a prefix. This style is common with
Protobuf (since it's heavily tied to C++ name resolution), however it's
non-idiomatic in Rust. To restore the previous behavior a new Config option is
provided: retain_enum_prefix. This is a breaking change.
@danburkert added helper methods for working with length delimiters
independently of message encoding and decoding.
And many more bug fixes.

Many thanks to the generous contributors who have helped out since 0.3.0:
