ExchangeUnbind unbinds the destination exchange from the source exchange on the server by removing the routing key between them. This is the inverse of ExchangeBind. If the binding does not currently exist, an error will be returned.
When noWait is true, do not wait for the server to confirm the deletion of the binding. If any error occurs the channel will be closed. Add a listener to NotifyClose to handle these errors.
Optional arguments that are specific to the type of exchanges bound can also be provided. These must match the same arguments specified in ExchangeBind to identify the binding.
