#
Returns: x.base() - y.base().
🔗
template<class Iterator> constexpr move_iterator<Iterator> operator+(iter_difference_t<Iterator> n, const move_iterator<Iterator>& x);
2
#
Constraints: x.base() + n is well-formed and has type Iterator.
3
#
Returns: x + n.

#
Effects: Equivalent to: return ranges​::​iter_move(i.current);

#
Effects: Equivalent to: ranges​::​iter_swap(x.current, y.current).
🔗
template<class Iterator> constexpr move_iterator<Iterator> make_move_iterator(Iterator i);
6
#
Returns: move_iterator<Iterator>(std​::​move(i)).
