std::shared...::owner_hash(3)

Okay bestie, welcome to the std::shared_ptr::owner_hash page from the C++ Standard Library manual — the header says C++ Standard Libary (typo and all, we stan 💀) and the page is std::shared...::owner_hash(3). ✨

💖 NAME 💖

std::shared_ptr::owner_hash — yeah, it’s literally std::shared_ptr::owner_hash. Main character function energy, no notes. 💅

✨ Synopsis ✨

std::size_t owner_hash() const noexcept;  (since C++26)

It returns an unspecified value such that, for any object other where owner_equal(other) is true, owner_hash() == other.owner_hash() is true. 🔥

This hashing is used to make shared and weak pointers usable as keys in unordered associative containers, typically through std::owner_hash. iykyk.

💖 Return value 💖

A value that is identical for any std::shared_ptr or std::weak_ptr object sharing the same ownership. Slay, consistency. 🫶

🧚 Notes 🧚

• Feature-test macro: __cpp_lib_smart_ptr_owner_equality
• Value: 202306L
• Std: (C++26)
