Rust implementation of gRPC protocol, under development.

Some development questions in FAQ.

It basically works. 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

Client and server are implemented asynchronously.

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

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

Readme

In Cargo.toml:

[dependencies]
grpc            = "~0.5"
protobuf        = "~2"
futures         = "~0.1"
futures-cpupool = "~0.1"

In lib.rs or main.rs (or any other submodule):

extern crate protobuf;
extern crate grpc;
extern crate futures;
extern crate futures_cpupool;

pub mod myproto;
pub mod myproto_grpc;

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

• grpc-rs — alternative implementation of gRPC in Rust, a wrapper to C++ implementation
• httpbis — implementation of HTTP/2, which is used by this implementation of gRPC
• rust-protobuf — implementation of Google Protocol Buffers
