![](https://github.com/hyperium/tonic/raw/master/.github/assets/tonic-banner.svg?sanitize=true)

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.runBuildScripts": true` to correctly load
the generated code.

For IntelliJ IDEA users, please refer to [this](https://github.com/intellij-rust/intellij-rust/pull/8056) and enable
`org.rust.cargo.evaluate.build.scripts`
[experimental feature](https://plugins.jetbrains.com/plugin/8182-rust/docs/rust-faq.html#experimental-features).

### Rust Version

`tonic` currently works on Rust `1.56` and above as it requires support for the 2018 edition.

```bash
$ rustup update
$ cargo build
```

### Tutorials

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

## 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][chat]. We would be happy to try to answer your
question. If that doesn't work, try opening an [issue] with the question.

## Project Layout

- [`tonic`](https://github.com/hyperium/tonic/tree/master/tonic): Generic gRPC and HTTP/2 client/server
implementation.
- [`tonic-build`](https://github.com/hyperium/tonic/tree/master/tonic-build): [`prost`] based service codegen.
- [`tonic-types`](https://github.com/hyperium/tonic/tree/master/tonic-types): [`prost`] based grpc utility types
  including support for gRPC Well Known Types.
- [`tonic-health`](https://github.com/hyperium/tonic/tree/master/tonic-health): Implementation of the standard [gRPC
health checking service][healthcheck]. Also serves as an example of both unary and response streaming.

reflection implementation.
- [`examples`](https://github.com/hyperium/tonic/tree/master/examples): Example gRPC implementations showing off
tls, load balancing and bi-directional streaming.
- [`interop`](https://github.com/hyperium/tonic/tree/master/interop): Interop tests implementation.
