23.5 Iterator adaptors [predef.iterators]

23.5.6 Counted iterators [iterators.counted]

23.5.6.7 Customizations [counted.iter.cust]

friend constexpr iter_rvalue_reference_t<I> iter_move(const counted_iterator& i) noexcept(noexcept(ranges::iter_move(i.current))) requires input_iterator<I>;
Effects: Equivalent to: return ranges​::​iter_­move(i.current);
template<indirectly_swappable<I> I2> friend constexpr void iter_swap(const counted_iterator& x, const counted_iterator<I2>& y) noexcept(noexcept(ranges::iter_swap(x.current, y.current)));
Effects: Equivalent to ranges​::​iter_­swap(x.current, y.current).
