Detailed Description

This class contains a collection of static functions for reading and writing simple types, in network byte order (MSB first).

It also contains functions to read and write strings. It also contains function templates to read and write arrays, deques, lists, vectors, maps, multimaps, sets, multisets, unordered_maps, unordered_multimaps, unordered_sets, unordered_multisets, tuples and variants. We use our member functions to handle reading and writing simple types in the containers, and function templates to handle reading and writing other class types. For a user-defined class, the class must implement the DescriptorReadable and DescriptorWritable interfaces, since our function templates simply call out to them. Since templates are static polymorphism, you don't need to inherit from DescriptorReadable and DescriptorWritable, but you must implement the interfaces.
