std::ranges...view::begin(3)

std::ranges...view::begin(3) 💅✨

C++ Standard Libary, bestie — manual name folded in right here, exactly as the header had it. We’re talking about std::ranges::chunk_view::begin, and it’s giving “start of the chunk view” energy.

---

🌸 NAME 🌸

std::ranges::chunk_view::begin — std::ranges::chunk_view::begin

✨ Synopsis ✨

Here are the overloads, preserved exactly, with their little version tags:

V models only input_range
constexpr __outer_iterator begin();
(1) (since C++23)

V models forward_range
constexpr auto begin() requires (!__simple_view<V>);
(2) (since C++23)

constexpr auto begin() const requires ranges::forward_range<const
V>;
(3) (since C++23)

Returns an iterator to the first element of the chunk_view.

Let base_ denote the underlying view.

1. Available only if V models input_range. Equivalent to:

current_ = ranges::begin(base_);
remainder_ = n_;
return __outer_iterator(*this);

current_, remainder_, and n_ are underlying exposition only data members of chunk_view.

2. Available if V models forward_range. Equivalent to:

return iterator<false>(this, ranges::begin(base_));

where iterator is exposition only nested class.

3. Available if V models forward_range. Equivalent to:

return iterator<true>(this, ranges::begin(base_));

where iterator is exposition only nested class.

🎀 Parameters 🎀

(none) — literally none, bestie.

🦋 Return value 🦋

An iterator to the first element of the chunk_view, as described above.
