When a message arrives at the delivery exchange, it must be forwarded to the original exchange and queue. To accomplish this, the function retrieves the exchange or binding objects associated with the queue and binds them to the delivery exchange. :param connection: The connection object used to create and manage the channel. :type connection: Connection :param queue: The queue to be bound to the native delayed delivery exchange. :type queue: Queue Warning: ------- If a direct exchange is detected, a warning will be logged because native delayed delivery does not support direct exchanges. )r% argumentsdirectz Exchange z is a direct exchange and native delayed delivery do not support direct exchanges.
