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

👑 std::ranges..._view::begin(3) 👑

okay bestie, this is the std::ranges::lazy_split_view::begin(3) page from the C++ Standard Libary manual — yes, “Libary” is literally how it’s written in the manual name, no cap, and we’re keeping it exactly like that 💅.

✨ NAME ✨

std::ranges::lazy_split_view::begin — std::ranges::lazy_split_view::begin (the name is the whole vibe, icon behavior 👑).

🦋 Synopsis 🦋

Two overloads, both marked (since C++20):

constexpr auto begin();

(1) (since C++20)

constexpr auto begin() const
  requires ranges::forward_range<V> && ranges::forward_range<const V>;

(2) (since C++20)

It returns an outer_iterator to the first element of the lazy_split_view ✨.

Let base_ be the underlying view.

1. Equivalent to:

constexpr auto begin() {
  if constexpr (ranges::forward_range<V>)
    return /*outer_iterator*/</*simple_view*/<V>>{*this, ranges::begin(base_)};
  else {
    current_ = ranges::begin(base_);
    return /*outer_iterator*/<false>{*this};
  }
}

2. Equivalent to return /*outer_iterator*/<true>{*this, ranges::begin(base_)};.

🎀 Parameters 🎀

• (none) — literally none, bestie. No args, no stress 🫶.

🌸 Return value 🌸

• outer_iterator to the first element.

🍓 Example 🍓
