Bir WebSocket bağlantısı kapandığında, `await websocket.receive_text()` bir `WebSocketDisconnect` exception'ı raise eder; ardından bunu bu örnekteki gibi yakalayıp (catch) yönetebilirsiniz.

 * <h2>Subscriber Methods</h2>
 *
 * <p>Event subscriber methods must accept only one argument: the event.
 *
 * <p>Subscribers should not, in general, throw. If they do, the EventBus will catch and log the
 * exception. This is rarely the right solution for error handling and should not be relied upon; it
 * is intended solely to help find problems during development.
