Public Member Functions
template<class packer_t >
index_t	aux_depends_on (const packer_t &other)
	this allows to share auxiliary data with other packer THE PACKERS MUST BE SYNCRONIZED EXTERNALLY: next_group must be called in sync with parent packer USE WITH CARE
template<class rec_it >
index_t	next_group (rec_it beg, index_t n=1)
	put a group of n elements starting from beg packing the group with 0 elements will lead to the following behaviour when unpacked: get_group_count(it) will return 0, *it will return the next recorded element (if it exists) then after ++it, *it will return the same element, but get_group_count(it) will return the next group count THE ELEMENTS POINTED BY BEG WILL NOT BE RECORDED WHEN n=0 DO NOT USE *it if get_group_count(it) returns 0!
std::size_t	packed_size () const
	returns the size in bytes ignoring vector overheads
std::size_t	data_size () const
	returns full unpacked sequence size in bytes
