+title: gRPC-Rust Preview Release
+date: 2026-05-28
+spelling: cSpell:ignore Tokio
+author:
+  name: Doug Fawley
+  position: Google
+---
+
+Today, the gRPC project is excited to share its first preview release of
+gRPC-Rust.  It can be found at
+[crates.io/crates/grpc](https://crates.io/crates/grpc).  Documentation is
+available on our website, [grpc.io](https://grpc.io/docs/languages/rust).  This
+release is not recommended for production use at this time, but is being
+released at an early stage to provide Rust programmers with an opportunity to
+experiment with the APIs and ensure they will be acceptable for their needs.
+
+## What is included
+
+This release includes:
+
+* **gRPC Client APIs**.  Includes all RPC types including unary and streaming.
+  * gRPC Server support is coming soon.
+
+* **Protobuf support** using Google's [Protobuf-Rust
+  library](https://github.com/protocolbuffers/protobuf) and tools.
+
+  * Messages are generated from Protobuf-Rust via `protoc`.
+  * gRPC generated RPC code using our `protoc` plugin.
+
+* **Low-level RPC API** for creating interceptors and performing RPCs without
+  the need for the protobuf generated code.
+
+* Support for the **[Tokio](https://tokio.rs/)** [async
+  runtime](https://rust-lang.github.io/async-book/08_ecosystem/00_chapter.html#async-runtimes).
+  * Future gRPC-Rust releases intend to work with any runtime; however, for this
+    preview we are only targetting Tokio.
+
+## Learn more
+
+Documentation for this gRPC-Rust preview can be found on
+[grpc.io](https://grpc.io/docs/languages/rust/).  The following resources are
+available:
+
+* [Generated code reference](https://grpc.io/docs/languages/rust/generated-code)
+* [Quick start guide](https://grpc.io/docs/languages/rust/quickstart)
+* [Basics tutorial](https://grpc.io/docs/languages/rust/basics) that covers each
+  of the four RPC types.
+

+others in the industry, or maybe even sharing your own experiences or advice in
+a talk, please mark your calendar for **Thursday, September 3rd**, when we'll be
+holding this year's gRPC developer's conference at the [Computer History
+Museum](https://computerhistory.org/) in Mountain View, CA.
