Re: [Boost-users] [serialization] size_t vs unsigned warnings

Hi

Line 36 in collections_save_imp.hpp says:

unsigned int count = s.size();

I'm getting many pages of warnings in VC++2005 stemming from this line. Would it make sense to change that to

std::size_t count = s.size() ?

No. size_t is a typedef. It could map to unsigned int on one version of the compiler and to unsigned long on another. Saving something as an unsigned int and loading it as an unsigned long is not guaranteed to work. By making this change, you may be introducing a subtle forward compatibility issue into your data files.
