Module sample 

Types representing received DDS samples and their associated metadata.

A received sample is either a full data sample of type T or a key-only sample carrying the instance key T::Key.

This distinction arises in DDS when an instance is disposed or unregistered, the reader receives a notification carrying only the key rather than a full payload.

Samples are obtained via Reader::peek, Reader::read, and Reader::take, or their equivalents on ReadCondition and QueryCondition.
