Helper classes

formatter<std::chrono::weekday_indexed>

 

template <class CharT, class Traits> std::basic_ostream<CharT, Traits>& operator<<(std::basic_ostream<CharT, Traits>& os, const std::chrono::weekday_indexed& wdi);		(since C++20)

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

if (wdi.index() >=1 && wdi.index <= 5) {
    os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{}[{}]"),
                      wdi.weekday(), wdi.index());
} else {
    os << std::format(os.getloc(), STATICALLY_WIDEN<CharT>("{}[{} is not a valid index]"),
                      wdi.weekday(), wdi.index());
}

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

Return value

os.
