STD::__IS_LOCATION_INVARIANT(3)

💖 std::__is_location_invariant< _Tp > 💖

okay bestie, welcome to the Library Functions Manual section of the libstdc++ docs, and lemme tell you about this absolute niche little trait, std::__is_location_invariant< _Tp > ✨ it's giving "internal compiler-adjacent lore" and honestly? iconic.

🌸 NAME 🌸

std::__is_location_invariant< _Tp > — the trait that sniffs out whether a type is "location-invariant" 🦋

---

✨ SYNOPSIS ✨

#include <functional>

---

👑 Detailed Description 👑

template<typename _Tp>
    struct std::__is_location_invariant< _Tp >

so basically, this trait is the one that says "hey, is this type location-invariant?" 💅 and what does that even mean, you ask? it means that the address of the object — or the address of any of its members — will not escape 🚫🚪 like, that pointer is NOT leaving the function, no cap, it stays home, it's a homebody, it has no main character energy in the address-leaking department.

and the tea is: trivially copyable types are location-invariant ✅ so if your type is trivially copyable, congrats bestie, you're in the club, no further work required 🎀

but also — and this is the fun part — users can specialize this trait for other types 🔥 so if you've got a type that's not trivially copyable but is still, like, spiritually location-invariant, you can go ahead and specialize it yourself. you have permission. go off 👑

fr fr though, this is an internal trait (look at those lil underscores), so treat it like the backstage pass that it is — know it exists, respect it, don't go feral with it 🫶

okay that's the whole page!! libstdc++ really said "here's one (1) trait, enjoy" and we did enjoy it 🌈 mwah, thanks for reading, this was the std::__is_...iant< _Tp >(3) page and it's a wrap 💖🎀🦋
