base on A native gRPC client & server implementation with async/await support.  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. [](https://crates.io/crates/tonic) [](https://docs.rs/tonic) [](LICENSE) [Examples] | [Website] | [Docs] | [Chat][discord] ## 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. ### Rust Version `tonic`'s MSRV is `1.71.1`. ### Dependencies [`tonic-build`] uses `protoc` [Protocol Buffers compiler] in some APIs which compile Protocol Buffers resource files such as [`tonic_build::compile_protos()`]. [Protocol Buffers compiler]: https://protobuf.dev/downloads/ [`tonic_build::compile_protos()`]: https://docs.rs/tonic-build/latest/tonic_build/fn.compile_protos.html ### 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][discord]. We would be happy to try to answer your question. If that doesn't work, try opening an [issue] with the question. [issue]: https://github.com/hyperium/tonic/issues/new/choose ## Project Layout - [`tonic`]: Generic gRPC and HTTP/2 client/server implementation. - [`tonic-build`]: [`prost`] based service codegen. - [`tonic-types`]: [`prost`] based grpc utility types including support for gRPC Well Known Types. - [`tonic-health`]: Implementation of the standard [gRPC health checking service][healthcheck]. Also serves as an example of both unary and response streaming. - [`tonic-reflection`]: A tonic based gRPC reflection implementation. - [`examples`]: Example gRPC implementations showing off tls, load balancing and bi-directional streaming. - [`interop`]: Interop tests implementation. ## Contributing :balloon: Thanks for your help improving the project!
