std::ranges::enumerate_view<V>::iterator<Const>::iterator

/*iterator*/()
    requires std::default_initializable<ranges::iterator_t<Base>> = default;
 (1) (since C++23) 
constexpr /*iterator*/( /*iterator*/<!Const> i )
    requires Const &&
        std::convertible_to<ranges::iterator_t<V>, ranges::iterator_t<Base>>;
 (2) (since C++23) 
private:
constexpr explicit /*iterator*/( ranges::iterator_t<Base> current,
                                 difference_type pos);
 (3) (exposition only*)

Construct an iterator.

1) Default constructor. Value-initializes the underlying iterator current_ with ranges::iterator_t<Base>() and the underlying index pos_ with ​0​.
2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes current_ with std::move(i.current_) and pos_ with i.pos_.
3) A private constructor which is used by enumerate_view::begin and enumerate_view::end. This constructor is not accessible to users. Initializes current_ with std::move(current) and pos_ with pos.

Parameters

i - an /*iterator*/<false>
