def closed?
  wrap_impl(@impl.closed?)
end

#expect_event(event, predicate: nil, timeout: nil, &block) ⇒ Object

Waits for event to fire and passes its value into the predicate function. Returns when the predicate returns truthy value. Will throw an error if the webSocket is closed before the event is fired. Returns the event data value.

#wait_for_event(event, predicate: nil, timeout: nil, &block) ⇒ Object

> NOTE: In most cases, you should use [‘method: WebSocket.waitForEvent`].

Waits for given ‘event` to fire. If predicate is provided, it passes event’s value into the ‘predicate` function and waits for `predicate(event)` to return a truthy value. Will throw an error if the socket is closed before the `event` is fired.
