In many cases using memcpy() is faster than copying array of objects one by
one. NTL (http://www.ntllib.org/) claims huge performance gains over STL
using it.
Type traits library may be extended with:
- memcpy_copyable<> and
- memcpy_moveable<>
These traits will be specialised for primitive types, pointers,
std::complex, etc. and users will be able to define then for their own
types. Some types may be moveable but not copyable (e.g. typical
std::string).
Containers and algorithms then can take advantage of memcpy() where
possible.
While it is possible for each individual library define such a traits,
having them in Boost.TypeTraits would make them (pseudo)standard.
