std::chrono...ekday_last)(3)

💖 NAME 💖

Bestie, welcome to the C++ Standard Libary page for std::chrono::operator<<(std::chrono::month_weekday_last) — yes, that's the manual name with the iconic spelling, and we're keeping it exactly. The NAME line is literally:

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

So yeah, same name twice. It's giving main-character energy, and honestly? Obsessed. 💅

✨ Synopsis ✨

Here's the exact signature-and-behavior situation, no cap:

          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::month_weekday_last& mwdl );

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

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

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

So it outputs a textual representation of mwdl into os, as if by that os << std::format(...) call. And the STATICALLY_WIDEN<CharT>("{:L}/{:L}") bit is "{:L}/{:L}" when CharT is char, and L"{:L}/{:L}" when CharT is wchar_t. Slay. 💖

💫 Return value 💫

It returns os. That's it. The stream comes back to you like a boomerang, bestie. 🪃
