std::enable...k_from_this(3)

okay bestie, you're reading the std::enable...k_from_this(3) page from the C++ Standard Libary manual. grab a strawberry 🍓 and let's get into it.

🌸 NAME 🌸

std::enable_shared_from_this::weak_from_this - std::enable_shared_from_this::weak_from_this

yes, it really lists it twice, and we are not erasing a single crumb. 💅

✨ Synopsis ✨

std::weak_ptr<T> weak_from_this() noexcept;             (1) (since C++17)
std::weak_ptr<T const> weak_from_this() const noexcept; (2) (since C++17)

so what does it do? it returns a std::weak_ptr<T> that tracks ownership of *this by all existing std::shared_ptr that refer to *this. iconic behavior, honestly. ✨

💖 Return value 💖

a std::weak_ptr<T> that shares ownership of *this with pre-existing std::shared_ptrs. periodt. 🫶

🧚 Notes 🧚

weak_from_this copies the exposition only weak_ptr member that is part of enable_shared_from_this.
