std::chrono::operator<< (std::chrono::weekday)

template <class CharT, class Traits>
std::basic_ostream<CharT, Traits>&
operator<<(std::basic_ostream<CharT, Traits>& os, const std::chrono::weekday& wd);

If !wd.ok(), equivalent to os << unsigned(wd) << " is not a valid weekday";. Otherwise, forms a std::basic_string<CharT> s consisting of the abbreviated weekday name for the weekday represented by wd, determined using the locale associated with os, and inserts s into os.

Return value

os.

Notes

This operator<< is primarily intended for debugging use. For control over formatting, use std::chrono::format.
