Helper classes

formatter<std::chrono::month_weekday>

hash<std::chrono::month_weekday> (C++26)

 

Defined in header <chrono>
template< class CharT, class Traits > std::basic_ostream<CharT, Traits>&     operator<<( std::basic_ostream<CharT, Traits>& os,                 const std::chrono::month_weekday& mwd );		(since C++20)

Outputs a textual representation of mwd into os, as if by

os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{:L}/{:L}"),
                  mwd.month(), mwd.weekday_indexed());

where STATICALLY_WIDEN<CharT>("{:L}/{:L}") is "{:L}/{:L}" if CharT is char, and L"{:L}/{:L}" if CharT is wchar_t.

Return value

os
