Library to read and write protocol buffers data

Features

This crate has one feature, which is with-bytes.

with-bytes enables protobuf crate support for bytes crate: when parsing bytes or strings from bytes::Bytes, protobuf will be able to reference the input instead of allocating subarrays.

Note, codegen also need to be instructed to generate Bytes or Chars for bytes or string protobuf types instead of default Vec<u8> or String, just enabling option on this crate is not enough.

See Customize struct in protobuf-codegen crate.
