💖 NAME 💖

okay so bestie, gather round — std::ranges::not_equal_to is a ranges::not_equal_to function object type. that's the whole vibe. she's a little type that you can call like a function, and she's living in the ranges era of C++ because of course she is. 💅

✨ SYNOPSIS ✨

#include <functional>

like, that's it. that's the include. go off, <functional>. 🎀

🌸 Public Types 🌸

  • using is_transparent — yes queen, she's transparent, meaning she plays nice with heterogeneous comparisons and doesn't force everything into one type first. iconic behavior, honestly.

🦋 Static Public Member Functions 🦋

  • template<typename _Tp, typename _Up> static constexpr bool operator()(_Tp &&__t, _Up &&__u) noexcept(noexcept(std::declval< _Tp >()==std::declval< _Up >()))

this is the main character moment right here. static, constexpr, templated on _Tp and _Up, takes __t and __u as forwarding references, and the noexcept spec literally just copies whatever std::declval< _Tp >()==std::declval< _Up >() does. so if == can throw, she can throw. if == is chill, she's chill. no cap. 🫶

ngl the noexcept(noexcept(...)) nesting is giving inception but it's literally just "inherit the exception-ness of the underlying == operator." periodt.

🔥 Detailed Description 🔥

ranges::not_equal_to function object type. 💀

she's the callable you reach for when you want to know if two things are not equal, but in a fancy ranges-flavored, transparent, constexpr, perfectly-forwarded kind of way. the way that she just works as a function object... obsessed. 🌈

👑 Author 👑

Generated automatically by Doxygen for libstdc++ from the source code. so like, no human author, just Doxygen doing its little robot thing and producing this page for us. we love an automated queen. 🤖✨

and that's the whole page bestie!! this absolute baddie shipped with libstdc++ and lives at std::range...ot_equal_to(3) in the manual — she got auto-generated by Doxygen straight from the source code and she's serving constexpr transparency realness. slay, read her, use her, love her. 🎀💖🦋⭐
