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

Hey bestie! 💖 Welcome to std::ranges...r::iterator(3), straight from the C++ Standard Libary — yes, that spelling is literally on the page, no cap. This manual is all about std::ranges::elements_view::iterator::iterator, and we're gonna construct it together. Let's go! ✨

🌸 NAME 🌸

std::ranges::elements_view::iterator::iterator — and also std::ranges::elements_view::iterator::iterator. She said it twice, and honestly? Iconic repetition. 😌

✨ Synopsis ✨

Okay so here's the constructor menu, bestie. Three overloads, all (since C++20), and the page labels them (1), (2), and (3). 🫶

/*iterator*/() requires
std::default_initializable<ranges::iterator_t<Base>>
= default;

(1) (since C++20)

constexpr explicit /*iterator*/( ranges::iterator_t<Base> current );

(2) (since C++20)

constexpr /*iterator*/( /*iterator*/<!Const> i ) requires Const &&
std::convertible_to<ranges::iterator_t<V>,
ranges::iterator_t<Base>>;

(3) (since C++20)

Construct an iterator. That's the whole vibe. 🎀

1. Value-initializes the underlying iterator current_ via its default member initializer (= ranges::iterator_t<Base>()). Cute default-initialization moment, fr fr.
2. Initializes the underlying iterator current_ with std::move(current). Moving, slaying, periodt.
3. Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes the underlying iterator current_ with std::move(i.current). Glow-up conversion energy. 💅

💖 Parameters 💖

• current — an iterator into (possibly const-qualified) V.
• i — an /*iterator*/<false>.
