Detailed Description

template<class T>
class cereal::SizeTag< T >

A wrapper around size metadata.

This class provides a way for archives to have more flexibility over how they choose to serialize size metadata for containers. For some archive types, the size may be implicitly encoded in the output (e.g. JSON) and not need an explicit entry. Specializing serialize or load/save for your archive and SizeTags allows you to choose what happens.

Creates a size tag from some variable.

Will normally be used to serialize size (e.g. size()) information for variable size containers. If you have a variable sized container, the very first thing it serializes should be its size, wrapped in a SizeTag.
