std::chrono::operator<<(std::chrono::year_month_weekday)

template< class CharT, class Traits >
std::basic_ostream<CharT, Traits>&
    operator<<( std::basic_ostream<CharT, Traits>& os,
                const std::chrono::year_month_weekday& ymwd );

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

os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{}/{:L}/{:L}"),
ymwd.year(), ymwd.month(), ymwd.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
