Kafka::Producer::DeliveryReport
Inherits Reference < Object
Class methods
callback
Returns a callback to be used when a message is delivered to a broker.
This logs the message payload that was delivered. The message arrives by pointer (see the conf_set_dr_msg_cb binding); the payload is not NUL-terminated, so the string is built with the message length. When err is set, librdkafka reuses the payload field for the error string.
