Detailed Description

This file defines the Serializer template class which encodes and decodes specific message types. The Reader class decodes messages and from a buffer and the Writer class encodes messages and writes them to a buffer. It also declares macros for declaring Messages. The Message class maps ROS messages types to class and message ID(s).

This namespace is for u-blox message serialization.
