A rust implementation of gRPC, a high performance, open source, general RPC framework that puts mobile and HTTP/2 first.

Note: tonic's master branch is currently preparing breaking changes. For the most recently released code, look to the 0.14.x branch.

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

  • 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.

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.

Rust Version

tonic's MSRV is 1.75.

Dependencies

tonic-build uses protocProtocol Buffers compiler in some APIs which compile Protocol Buffers resource files such as tonic_build::compile_protos().

Getting Help

First, see if the answer to your question can be found in the API documentation. If the answer is not there, there is an active community in the Tonic Discord channel. We would be happy to try to answer your question. If that doesn't work, try opening an issue with the question.

A rust implementation of gRPC, a high performance, open source, general
RPC framework that puts mobile and HTTP/2 first.
Note: tonic's master branch is
currently preparing breaking changes. For the most recently released code,
look to the 0.14.x branch.
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
  • 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.
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.
Rust Version
tonic's MSRV is 1.75.
Dependencies
tonic-build uses protocProtocol Buffers compiler in some APIs which compile Protocol Buffers resource files such as tonic_build::compile_protos().
Getting Help
First, see if the answer to your question can be found in the API documentation.
If the answer is not there, there is an active community in
the Tonic Discord channel. We would be happy to try to answer your
question. If that doesn't work, try opening an issue with the question.
