fastwebsockets is a fast, minimal RFC6455 WebSocket implementation in Rust, usable as a raw frame parser or as a full client/server with optional hyper-based HTTP upgrade support. It passes the Autobahn|TestSuite, is fuzzed with libFuzzer, and offers optional SIMD-accelerated UTF-8 validation.
Use cases
- implement a websocket server in rust
- parse raw websocket frames
- add websocket support to a hyper or axum service
- build a websocket client with handshake support
- handle websocket fragmentation and auto ping/close
When to choose
- you need a fast, spec-compliant websocket implementation in a tokio-based Rust app
- you want low-level control over websocket frames
- you're integrating websockets into hyper/axum via HTTP upgrade
When to avoid
- you need permessage-deflate compression, which is not yet supported
- you want a batteries-included websocket solution with automatic message reassembly by default
- you're not using async Rust/tokio
