A reliable publisher that

Queues up messages internally until it can successfully call basicPublish.
Notifies the caller using a robust ID (not delivery tag) when the message is confirmed by rabbit.

This is a layer above the RabbitMQClient that provides a lot of standard implementation when guaranteed at least once delivery is required.
If confirmations are not required do not use this publisher as it does have overhead.
 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**
