std::identity(3)

💖 NAME 💖

std::identity — [func.identity] The identity function. bestie it literally just hands you back whatever you gave it, no notes, no edits, no glow-up, just you but as a function 🪞✨

(this is std::identity(3), from the Library Functions Manual, in case you were wondering which manual section we're living in 💅)

🎀 SYNOPSIS 🎀

#include <functional>

✨ Public Types ✨

• using is_transparent

🌸 Static Public Member Functions 🌸

• template<typename _Tp> static constexpr _Tp && operator() (_Tp &&__t) noexcept

okay so that signature? lowkey iconic. constexpr, noexcept, perfect forwarding, a template parameter named _Tp — she's doing the absolute most and giving absolutely nothing back, which is exactly the point 💀👑
