Helper classes

formatter<std::chrono::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::weekday_last& wdl );		(since C++20)

Outputs a textual representation of wdl into the stream os, as if by

os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{:L}[last]"), wdl.weekday());

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

Return value

os.
