NAME¶

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

Synopsis¶

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::year_month_weekday_last& ymwdl );

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.
