Helper classes

formatter<std::chrono::year_month_weekday_last>

 

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

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

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

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

Return value

os.
