## What it is
tokio-tungstenite is a Rust library providing asynchronous WebSocket client and server support built on top of the lightweight tungstenite-rs implementation, with Tokio bindings for non-blocking streams. It supports TLS via native-tls or rustls feature flags for secure wss:// connections.

## Use cases
- add websocket support to a tokio server
- connect to a websocket api from rust asynchronously
- build a real-time chat backend in rust
- stream messages over wss with rustls
- implement a lightweight websocket client without heavy frameworks

## When to choose
- you are already using the Tokio async runtime
- you want a lightweight, stream-based WebSocket implementation in Rust
- you need TLS support via native-tls or rustls feature flags
- you need a mature, widely used WebSocket crate with production track record

## When to avoid
- you need maximum WebSocket throughput and prefer fastwebsockets
- you use an async runtime other than Tokio
- you want a full-featured web framework with WebSockets built in

## Facets
- artifact type: library
- maturity: stable
- function: websocket, http-server, http-client, networking
- domain: web-development, backend, networking
- platform: rust, cross-platform
- tags: websocket, tokio, async, rust, tls, wss, real-time
