# 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](https://github.com/tokio-rs/bytes):
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](https://docs.rs/protobuf-codegen).
## Accompanying crates
* [`protobuf-json-mapping`](https://docs.rs/protobuf-json-mapping)
implements JSON parsing and serialization for protobuf messages.
* [`protobuf-codegen`](https://docs.rs/protobuf-codegen)
can be used to generate rust code from `.proto` crates.
* [`protoc-bin-vendored`](https://docs.rs/protoc-bin-vendored)
contains `protoc` command packed into the crate.
* [`protobuf-parse`](https://docs.rs/protobuf-parse) contains
`.proto` file parser. Rarely need to be used directly,
but can be used for mechanical processing of `.proto` files.
