## What it is
Rust-WebSocket is a Rust library implementing the WebSocket protocol (RFC6455) for both client and server connections, with message-level and data-frame-level APIs and support for secure WebSockets. The project is effectively in maintenance mode and its own README recommends using tungstenite or tokio-tungstenite instead, since it depends on obsolete versions of Hyper and Tokio.

## Use cases
- implement a websocket server in rust
- connect to a websocket endpoint from rust
- handle websocket message fragmentation
- add secure wss connections to a rust app
- work with raw websocket data frames
- test websocket conformance against autobahn suite

## When to choose
- you are maintaining an existing codebase already built on rust-websocket
- you need a pure-rust RFC6455 implementation with a frame-level API and cannot switch libraries

## When to avoid
- starting a new Rust project (use tungstenite or tokio-tungstenite instead)
- you need async support on modern Tokio versions
- you need actively maintained code with timely bug fixes

## Facets
- artifact type: library
- maturity: maintenance
- function: websocket, http-server, http-client, networking
- domain: web-development, backend, networking
- platform: rust, cross-platform
- tags: rfc6455, websocket-client, websocket-server, deprecated, legacy-dependencies, real-time
