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\&.
