Rust-WebSocket

Rust-WebSocket is a WebSocket (RFC6455) library written in Rust.

Note that this particular library is based on obsolete dependencies (Hyper 0.10, Tokio 0.1), so is a poor choice for new projects. You are adviced to use other Websocket libraries.

Rust-WebSocket provides a framework for dealing with WebSocket connections (both clients and servers). The library is currently in an experimental state, but provides functionality for both normal and secure WebSockets, a message level API supporting fragmentation, a data frame level API, and the ability to extend and customize behaviour.

Installation

To add a library release version from crates.io to a Cargo project, add this to the 'dependencies' section of your Cargo.toml:

websocket = "0.24.0"

To add the library's Git repository to a Cargo project, add this to your Cargo.toml:

[dependencies.websocket]

git = "https://github.com/websockets-rs/rust-websocket.git"

Optionally add extern crate websocket; to your project.

Note that 0.24.0 is the last version of rust-websocket that supports some very old Rust versions (I'm not sure which exactly, maybe 1.28).

Usage

The library can be compiled with tests and benches and some extra capabilities on Rust nightly. To enable the nightly features, use cargo --features nightly ....

See the documentation for the latest release of the library here, and also the examples, which are located in /examples and can be run with:

cargo run --example server

And in a separate terminal:

cargo run --example client

Testing

The library can be tested using cargo test to run tests and cargo bench to run bench tests.

A number of tests are included, which ensure core WebSocket functionality works as expected. These tests are not yet comprehensive, and are still being worked on.

Autobahn TestSuite

Rust-WebSocket uses the Autobahn TestSuite to test conformance to RFC6455. If you have Autobahn TestSuite installed you can run these tests yourself using the commands:

wstest -m fuzzingserver
cargo run --example autobahn-client

To test the client implementation, and

wstest -m fuzzingclient
cargo run --example autobahn-server

To test the server implementation. The spec files are available here.

The results of these tests are available here.
