Biomodern.Serializer
is a C++20 generalized serializer that can serialize the continuous_range
which value_type
is trivially_copyable
, such as scalar type, simple struct
, array
etc. The binary archive file size is actually the memory occupation in run time plus one size_t
which indicates the size of the continuous container.
Furthermore, Biomodern.Serializer
can also serialize the vector<bool>
and still make the binary archive file size as small as the original memory occupation. This is hugely different from Boost.Serialization
which store the vector<bool>
as a vector<uint8_t>
even in binary_archive
mode.
The Biomodern.Serializer
can also serialize my other project Biomodern.DitbitVector
which is a space-efficient specialization of the vector
of two-bits numbers.
