DEFINE_LEXI_CAST_OVERLOAD

#define DEFINE_LEXI_CAST_OVERLOAD	(		TYPE,
			ABBREVIATION )

Value:

    template<>                                                                                                              \
    inline auto ::CppUtils::Strings::lexical_cast<TYPE, std::char_traits<char>>(const std::string& str)                     \
    {                                                                                                                       \
        return std::sto##ABBREVIATION(str);                                                                                 \
    }

A macro for creating specializations of the lexical_cast<> template where the standard library already has functions specificically for this purpose.

Note

A full specialization is possible here because it doesn't matter if the input string is case-sensitive or not, all we're looking for are the integers that make up the number.
