MessageId (TurtleQueue API)

All Superinterfaces:

Comparable<MessageId>

All Known Implementing Classes:

MessageIdImpl
```
public interface MessageId
extends Comparable<MessageId>
```
Opaque unique identifier of a single message
The MessageId can be used to reference a specific message, for example when acknowledging, without having to retain the message content in memory for an extended period of time.
Message ids are Comparable and a bigger message id will imply that a message was published "after" the other one.
