This is the main entry point for WebSocket connections. Use this as an Axum route handler by passing it to an Axum router’s .route() method with get().

Arguments

• ws - WebSocket upgrade from Axum
• State(state) - Application state containing the handler and optional schemas

Returns

An Axum response that upgrades the connection to WebSocket

Example

use axum::{Router, routing::get, extract::State};

let state = WebSocketState::new(MyHandler);
let router = Router::new()
    .route("/ws", get(websocket_handler::<MyHandler>))
    .with_state(state);
