23 Iterators library [iterators]

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).
