grpc-rust

Build Status License crates.io

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 google.golang.org/grpc/examples/helloworld/greeter_client
$ 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 google.golang.org/grpc/examples/helloworld/greeter_client
$ 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

(Recommended)

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

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

Readme

Use generated protos in your project

In Cargo.toml:

[dependencies]
grpc            = "~0.8"
protobuf        = "2.23"
futures         = "~0.3"

[build-dependencies]
protoc-rust-grpc = "~0.8"

TODO

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