The error() method of the WritableStreamDefaultController interface causes any future interactions with the associated stream to error.

This method is rarely used, since usually it suffices to return a rejected promise from one of the underlying sink's methods. However, it can be useful for suddenly shutting down a stream in response to an event outside the normal lifecycle of interactions with the underlying sink.
