std::hash(s...server_ptr)(3)

💖 std::hash(std::experimental::observer_ptr) 💖

okay bestie, welcome to the C++ Standard Libary manual, section 3. yes, the manual name is folded in right here — we are not copying the whole header line, we are curating it. this page is about the std::hash specialization for std::experimental::observer_ptr, and it's lowkey iconic. iykyk ✨

🏷️ NAME 🏷️

• std::hash(std::experimental::observer_ptr) — literally std::hash(std::experimental::observer_ptr). that's the name, no extra lore, periodt.

✨ SYNOPSIS ✨

Defined in header <experimental/memory> — put that in your notes, bestie.

Template vibes:

template< class T > struct
hash<std::experimental::observer_ptr<T>>;

and this is the (library fundamentals TS v2) flavor. 🫶

🌸 DESCRIPTION 🌸

The template specialization of std::hash for std::experimental::observer_ptr<T> is the glow-up that allows users to obtain hashes of objects of type std::experimental::observer_ptr<T>. slay.

For a given std::experimental::observer_ptr<T> p, this specialization ensures that

std::hash<std::experimental::observer_ptr<T>>()(p) == std::hash<T*>()(p.get())

no cap, that equality is the whole point. 💅
