@FunctionalInterface
public interface CancelCallback {

    /**
     * Called when the consumer is cancelled for reasons other than by a call to
     * {@link Channel#basicCancel}. For example, the queue has been deleted.
     * See {@link Consumer#handleCancelOk} for notification of consumer
     * cancellation due to {@link Channel#basicCancel}.
     * @param consumerTag the consumer tag associated with the consumer
     * @throws IOException
     */
    void handle(String consumerTag) throws IOException;

}
