~out_ptr_t(); |  | (since C++23)

Resets the adapted `Smart` object by the value of modified `Pointer` object (or the void* object if operator void**() has been called) and the captured arguments.

Let

- `s` denotes the adapted `Smart` object,
- `args...` denotes the captured arguments,
- `p` denotes the value of stored `Pointer`, or static_cast<Pointer>(*operator void**()) if operator void** has been called,
- `SP` be
  - Smart::pointer, if it is valid and denotes a type, otherwise,
  - Smart::element_type*, if Smart::element_type is valid and denotes a type, otherwise,
  - std::pointer_traits<Smart>::element_type*, if std::pointer_traits<Smart>::element_type is valid and denotes a type, otherwise,
  - `Pointer`.

If s.reset(static_cast<SP>(p), std::forward<Args>(args)...) is well-formed, the destructor performs

  if (p) s.reset(static_cast<SP>(p), std::forward<Args>(args)...);,

otherwise, if std::is_constructible_v<Smart, SP, Args...> is true, the destructor performs

  if (p) s = Smart(static_cast<SP>(p), std::forward<Args>(args)...);,

otherwise, the program is ill-formed.

### Notes

If `Smart` is a std::shared_ptr specialization, the implementation may allocate the storage for the new control block on construction, in order to leave non-throwing works to the destructor.

Arguments captured by value are destroyed after resetting.
