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.

Overview

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 hyper, 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 protobuf definitions.

Features

  • Bi-directional streaming
  • High performance async io
  • Interoperability
  • TLS backed by rustls
  • Load balancing
  • Custom metadata
  • Authentication
  • Health Checking

Getting Started

Examples can be found in examples and for more complex scenarios interop may be a good resource as it shows examples of many of the gRPC features.

If you're using rust-analyzer we recommend you set "rust-analyzer.cargo.buildScripts.enable": true to correctly load the generated code.

For IntelliJ IDEA users, please refer to this and enable org.rust.cargo.evaluate.build.scripts experimental feature.

Rust Version

tonic's MSRV is 1.64.

$ rustup update
$ cargo build

Dependencies

In order to build tonic >= 0.8.0, you need the protoc Protocol Buffers compiler, along with Protocol Buffers resource files.

Ubuntu

sudo apt update && sudo apt upgrade -y
sudo apt install -y protobuf-compiler libprotobuf-dev

Alpine Linux

sudo apk add protoc protobuf-dev

macOS

Assuming Homebrew is already installed. (If not, see instructions for installing Homebrew on the Homebrew website.)

brew install protobuf

Windows

  • Download the latest version of protoc-xx.y-win64.zip from HERE
  • Extract the file bin\protoc.exe and put it somewhere in the PATH
  • Verify installation by opening a command prompt and enter protoc --version

Tutorials

  • The helloworld tutorial provides a basic example of using tonic, perfect for first time users!
  • The routeguide tutorial provides a complete example of using tonic and all its features.
