Build Status License

Rust implementation of gRPC protocol, under development.

Some development questions in FAQ.

Current status

It basically works, but not suitable for production use.

See grpc-examples/src/bin/greeter_{client,server}.rs. It can be tested for example with go client:

# start greeter server implemented in rust
$ cargo run --bin greeter_server

# ... or start greeter server implemented in go
$ go get -u
$ greeter_server

# start greeter client implemented in rust
$ cargo run --bin greeter_client rust
> message: "Hello rust"

# ... or start greeter client implemented in go
$ go get -u
$ greeter_client rust
> 2016/08/19 05:44:45 Greeting: Hello rust

Route guide

Route guide example implementation in grpc-rust is in grpc-examples folder.

How to generate rust code

There are two ways to generate rust code from .proto files

Invoke protoc programmatically with protoc-rust-grpc crate


Have a look at readme in protoc-rust-grpc crate.

With protoc command and protoc-gen-rust-grpc plugin


Use generated protos in your project

In Cargo.toml:

grpc            = "~0.8"
protobuf        = "2.23"
futures         = "~0.3"

protoc-rust-grpc = "~0.8"


  • Fix performance
  • More tests
  • In particular, add more compatibility tests, they live in interop directory
  • Fix all TODO in sources
