constexpr atomic_weak_ptr() noexcept;
(1)
constexpr atomic_weak_ptr( weak_ptr<T> desired ) noexcept;
(2)
atomic_weak_ptr( const atomic_weak_ptr& ) = delete;
(3)

Constructs a new atomic_weak_ptr object.

1) The default constructor initializes the object to an empty state.
2) Initializes the underlying weak_ptr<T> with desired. The initialization is not atomic.
3) Atomic variables are not CopyConstructible.

Parameters

desired - value to initialize with
