# Tungstenite
|
|
|
|
|
|
|
|
Lightweight stream-based WebSocket implementation for [Rust](http://www.rust-lang.org).
|
|
|
|
|
|
|
|
```rust
|
|
|
|
|
|
|
|
/// A WebSocket echo server
|
|
|
|
let server = TcpListener::bind("127.0.0.1:9001").unwrap();
|
|
|
|
for stream in server.incoming() {
|
|
|
|
spawn (move || {
|
|
|
|
let mut websocket = accept(stream.unwrap(), None).unwrap();
|
|
|
|
loop {
|
|
|
|
let msg = websocket.read_message().unwrap();
|
|
|
|
|
|
|
|
// We do not want to send back ping/pong messages.
|
|
|
|
if msg.is_binary() || msg.is_text() {
|
|
|
|
websocket.write_message(msg).unwrap();
|
|
|
|
}
|
|
|
|
}
|
|
|
|
});
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
Take a look at the examples section to see how to write a simple client/server.

Introduction
|
|
|
|
------------
|
|
|
|
This library provides an implementation of WebSockets,
|
|
|
|
[RFC6455](https://tools.ietf.org/html/rfc6455). It allows for both synchronous (like TcpStream)
|
|
|
|
and asynchronous usage and is easy to integrate into any third-party event loops including
|
|
|
|
[MIO](https://github.com/carllerche/mio). The API design abstracts away all the internals of the
|
|
|
|
WebSocket protocol but still makes them accessible for those who wants full control over the
|
|
|
|
network.
|
|
|
|
|
|
|
|
This library is a work in progress. Feel free to ask questions and send us pull requests.

Why Tungstenite?
|
|
|
|
----------------
|
|
|
|
|
|
|
|
It's formerly WS2, the 2nd implementation of WS. WS2 is the chemical formula of
|
|
|
|
tungsten disulfide, the tungstenite mineral.
|
|
|
|
|
|
|
|
Features
|
|
|
|
--------
|
|
|
|
|
|
|
|
Tungstenite provides a complete implementation of the WebSocket specification.
|
|
|
|
TLS is supported on all platforms using native-tls.
|
|
|
|
|
|
|
|
There is no support for permessage-deflate at the moment. It's planned.
|
|
|
|
|
|
|
|
Testing
|
|
|
|
-------
|
|
|
|
|
|
|
|
Tungstenite is thoroughly tested and passes the [Autobahn Test Suite](http://autobahn.ws/testsuite/) for
|
|
|
|
WebSockets. It is also covered by internal unit tests as good as possible.
