std::chrono::operator<<(std::chrono::month_weekday_last) - std::chrono::operator<<(std::chrono::month_weekday_last)


Defined in header <chrono>
template <class CharT, class Traits>

std::basic_ostream<CharT, Traits>& (since C++20)
operator<<( std::basic_ostream<CharT, Traits>& os,

const std::chrono::month_weekday_last& mwdl );

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

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

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

Return value
