🌸 NAME 🌸

std::identity — like, the actual name section says it's [func.identity] The identity function. and honestly? that's the whole vibe. it takes a thing and gives you back the thing 💅

✨ SYNOPSIS ✨

ok bestie, first things first, you gotta invite it in:

#include <functional>

🎀 Public Types 🎀

• using is_transparent = __is_transparent — bestie it's transparent, it's giving see-through icon behavior, that's the whole type right there 👑

💜 Public Member Functions 💜

• template<typename _Tp > constexpr _Tp && operator() (_Tp &&__t) const with noexcept — the main character herself. she takes your _Tp and hands it right back, constexpr and noexcept and perfect-forwarded and everything 🫶

ngl bestie, this one's short and sweet — but that's the point. identity does one thing (returns __t), does it noexcept, and does it as a constexpr icon. periodt 💅
