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

🎀 std::hash(s...shared_ptr)(3) 🎀

okay bestie, welcome to the C++ Standard Libary manual page for std::hash(std::experimental::shared_ptr) — the (3) is right there, and the synopsis is serving library fundamentals TS realness. this page is all about the std::hash specialization for std::experimental::shared_ptr<T>, and it is lowkey iconic ✨.

💖 NAME 💖

std::hash(std::experimental::shared_ptr) — that's the name, and the page repeats it as std::hash(std::experimental::shared_ptr) too. double name, double main character energy 💅.

🌸 Synopsis 🌸

here's the synopsis exactly as it's doing its little line-break dance:

          template< class T > struct
       (library fundamentals
          hash<std::experimental::shared_ptr<T>>;                        TS)

the line breaks are canon, don't come for me 😭. this is the hash<std::experimental::shared_ptr<T>> specialization, and the synopsis is tagged with (library fundamentals ... TS).

then the tea: the template specialization of std::hash for std::experimental::shared_ptr<T> allows users to obtain hashes of objects of type std::experimental::shared_ptr<T> 🫶.

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

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

like, that equality is the whole vibe check. ⭐
