constexpr counted_iterator(I i, iter_difference_t<I> n);
Effects: Initializes
current with
std::move(i) and
length with
n. template<class I2>
requires convertible_to<const I2&, I>
constexpr counted_iterator(const counted_iterator<I2>& x);
Effects: Initializes
current with
x.current and
length with
x.length. template<class I2>
requires assignable_from<I&, const I2&>
constexpr counted_iterator& operator=(const counted_iterator<I2>& x);
Effects: Assigns
x.current to
current and
x.length to
length.
