std::ranges...or::iterator(3)

💖 NAME 💖

okay bestie, this page is about std::ranges::enumerate_view::iterator::iterator — and the NAME line literally says std::ranges::enumerate_view::iterator::iterator twice, which is giving "I have main character energy and also a long name" 💅. The header abbreviates it as std::ranges...or::iterator(3), and this is from the C++ Standard Libary manual, section 3. Lock in. ✨

✨ Synopsis ✨

here's the synopsis, no cap:

/*iterator*/()
    requires std::default_initializable<ranges::iterator_t<Base>> (1)
    (since C++23)
= default;

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. 🫶

🌸 Parameters 🌸

• i — an /*iterator*/<false>. that's the whole parameter list, bestie. 🎀

🦋 Constructors / Description 🦋

1. Default constructor. Value-initializes the underlying iterator current_ with ranges::iterator_t<Base>() and the underlying index pos_ with 0. cute, clean, zeroed out. ✨
2. Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes current_ with std::move(i.current_) and pos_ with i.pos_. yes, it's moving things, we love a transfer of energy. 💫
3. A private constructor which is used by enumerate_view::begin and enumerate_view::end. This constructor is not accessible to users — hands off, bestie. 🙈 It initializes current_ with std::move(current) and pos_ with pos.
