Today, the gRPC project is excited to share its first preview release of
gRPC-Rust. It can be found at 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.
