std::regex_traits<char> | |
std::regex_traits<wchar_t> |
Essas especializações tornar possível a utilização de std::basic_regex<char> (aka std::regex) e std::basic_regex<wchar_t> (aka std::wregex), mas, a fim de usar, por exemplo, std::basic_regex<char32_t>, fornecidos pelo utilizador std::regex_traits<char32_t> specializtion precisa de ser definida.
Original:
These specializations make it possible to use std::basic_regex<char> (aka std::regex) and std::basic_regex<wchar_t> (aka std::wregex), but in order to use, for example, std::basic_regex<char32_t>, user-provided specializtion std::regex_traits<char32_t> needs to be defined.
