A rust implementation of gRPC, a high performance, open source, general RPC framework that puts mobile and HTTP/2 first.
tonic is a gRPC over HTTP/2 implementation focused on high performance, interoperability, and flexibility. This library was created to have first class support of async/await and to act as a core building block for production systems written in Rust.
tonic is composed of three main components: the generic gRPC implementation, the high performance HTTP/2
implementation and the codegen powered by
prost. The generic implementation can support any HTTP/2
implementation and any encoding via a set of generic traits. The HTTP/2 implementation is based on
a fast HTTP/1.1 and HTTP/2 client and server built on top of the robust
tokio stack. The codegen
contains the tools to build clients and servers from
- Bi-directional streaming
- High performance async io
- TLS backed by
- Load balancing
- Custom metadata
- Health Checking
If you're using rust-analyzer we recommend you set
"rust-analyzer.cargo.buildScripts.enable": true to correctly load
the generated code.
tonic's MSRV is
$ rustup update $ cargo build
In order to build
tonic >= 0.8.0, you need the
protoc Protocol Buffers compiler, along with Protocol Buffers resource files.
sudo apt update && sudo apt upgrade -y sudo apt install -y protobuf-compiler libprotobuf-dev
sudo apk add protoc protobuf-dev
brew install protobuf
- Download the latest version of
- Extract the file
bin\protoc.exeand put it somewhere in the
- Verify installation by opening a command prompt and enter
