std::ranges::cartesian_product_view<First, Vs...>::iterator<Const>::iterator

/*iterator*/() = default;
 (1) (since C++23) 
constexpr /*iterator*/( /*iterator*/<!Const> i )
    requires Const && (
        std::convertible_to<ranges::iterator_t<First>, ranges::iterator_t<const First>>
        && ... &&
        std::convertible_to<ranges::iterator_t<Vs>, ranges::iterator_t<const Vs>>
    );
 (2) (since C++23) 
private:
constexpr /*iterator*/(
    /*Parent*/& parent,
    std::tuple<ranges::iterator_t</*maybe-const*/<Const, First>>,
               ranges::iterator_t</*maybe-const*/<Const, Vs>>...> current );
 (3) (exposition only*)

Construct an iterator.

1) Default constructor. Value-initializes the parent_ with nullptr and default-initializes the current_.
2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes parent_ with i.parent_ and current_ with std::move(i.current_).
3) A private constructor which is used by cartesian_product_view::begin and cartesian_product_view::end. This constructor is not accessible to users. Initializes parent_ with std::addressof(parent) and current_ with std::move(current).

Parameters

i - an /*iterator*/<false>
