Accesses the owned value.

1,2) Returns a pointer to the owned value.
3,4) Returns a reference to the owned value.

If * this is valueless, the behavior is undefined.

Return value

As described above.

Notes

This operator does not check whether * this is valueless, users can do so manually by using valueless_after_move() .
