Description:
 def _basic_deliver(self, args, msg):
 """Notify the client of a consumer message This method delivers a message to the client, via a consumer. In the asynchronous message delivery model, the client starts a consumer using the Consume method, then the server responds with Deliver methods as and when messages arrive for that consumer. RULE: The server SHOULD track the number of times a message has been delivered to clients and when a message is redelivered a certain number of times - e.g. 5 times - without being acknowledged, the server SHOULD consider the message to be unprocessable (possibly causing client applications to abort), and move the message to a dead letter queue. PARAMETERS: consumer_tag: shortstr consumer tag Identifier for the consumer, valid within the current connection. RULE: The consumer tag is valid only within the channel from which the consumer was created. I.e. a client MUST NOT create a consumer in one channel and then use it in another. delivery_tag: longlong server-assigned delivery tag The server-assigned and channel-specific delivery tag RULE: The delivery tag is valid only within the channel from which the message was received. I.e. a client MUST NOT receive a message on one channel and then acknowledge it on another. RULE: The server MUST NOT use a zero value for delivery tags. Zero is reserved for client use, meaning "all messages so far received". redelivered: boolean message is being redelivered This indicates that the message has been previously delivered to this or another client. exchange: shortstr Specifies the name of the exchange that the message was originally published to. routing_key: shortstr Message routing key Specifies the routing key name specified when the message was published.
