This implementation is approaching end of life. Official protobuf implementation (not based on this implementation) is on the way, that will be released as protobuf=4 soon. Follow progress in protobuf repository.
Protobuf implementation in Rust.
- Written in pure rust
- Generates rust code
- Has runtime library support for generated code (Coded{Input|Output}Stream impl)
- Supports both Protobuf versions 2 and 3
- and more
Documentation is hosted on docs.rs.
Version 3 is current stable version. Compared to version 2 it implements:
- runtime reflection
- JSON and text format parsing and printing
- dynamic messages (messages which can be created from
.protofile on the fly without code generation)
Version 2 is previous stable version. Only most critical bugfixes will be applied to 2.x version, otherwise it won't be maintained.
The crate needs help:
- a new maintainer, but also
- testing
- documentation
- examples to be used as documentation
- feedback on API design
- feedback on implementation
- pull requests
See CHANGELOG.md for a list of changes and compatility issues between versions.
- prost — another protobuf implementation in Rust, also has gRPC implementation
- quick-protobuf — alternative protobuf implementation in Rust
- grpc-rs — another gRPC implementation for Rust
- grpc-rust — incomplete implementation of gRPC based on this library
