std::experi...tr::weak_ptr(3)

🌸 NAME 🌸

okay bestie, welcome to std::experi...tr::weak_ptr(3) from the C++ Standard Libary manual — yes, “Libary” is literally what the header says, and we respect the typo 💅.

The NAME section is giving repetition main character energy: std::experimental::weak_ptr::weak_ptr — and then again, std::experimental::weak_ptr::weak_ptr. It’s the std::experimental::weak_ptr::weak_ptr constructor, periodt.

🎀 Synopsis 🎀

Constructs a new weak_ptr that potentially shares an object with r.

• (1) (library fundamentals TS)

constexpr weak_ptr() noexcept;

• (2) (library fundamentals TS)

weak_ptr( const weak_ptr& r ) noexcept;

• (2) (library fundamentals TS)

template< class Y >
weak_ptr( const weak_ptr<Y>& r ) noexcept;

• (2) (library fundamentals TS)

template< class Y >
weak_ptr( const std::experimental::shared_ptr<Y>& r ) noexcept;

• (3) (library fundamentals TS)

weak_ptr( weak_ptr&& r ) noexcept;

• (3) (library fundamentals TS)

template< class Y >
weak_ptr( weak_ptr<Y>&& r ) noexcept;

1. Default constructor. Constructs empty weak_ptr. Lowkey the simplest slay.
2. Constructs new weak_ptr which shares an object managed by r. If r manages no object, *this manages no object too. The templated overloads don't participate in overload resolution unless either Y* is implicitly convertible to T*, or Y is the type "array of N U" for some type U and some number N, and T is the type "array of unknown bound of (possibly cv-qualified) U". Yes bestie, that’s the whole vibe check 🫶.
3. Move constructors. Moves a weak_ptr instance from r into *this. After this, r is empty and r.use_count() == 0. The templated overload doesn't participate in overload resolution unless either Y* is implicitly convertible to T*, or Y is the type "array of N U" for some type U and some number N, and T is the type "array of unknown bound of (possibly cv-qualified) U". Same energy, singular overload edition ✨.
