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

std::ranges::enumerate_view::begin 💅

okay bestie, welcome to the C++ Standard Libary manual, section 3 — and we're hyping up std::ranges::enumerate_view::begin, the member function that hands you the iterator to the very first element of an enumerate_view. It's giving "start the range off right" main character energy ✨.

🌸 NAME 🌸

std::ranges::enumerate_view::begin — std::ranges::enumerate_view::begin. Yes bestie, the name is the name, and it's iconic 💖.

✨ Synopsis ✨

Here's the signature tea, copied with care:

          constexpr auto begin() requires (!__simple_view<V>);
       (1) (since C++23)
          constexpr auto begin() const requires
       (2) (since C++23)
          /*range-with-movable-references*/<const V>;

Returns an iterator to the first element of the enumerate_view.

Let base_ denote the underlying view.

1. Equivalent to return /*iterator*/<false>(ranges::begin(base_), 0);.
2. Equivalent to return /*iterator*/<true>(ranges::begin(base_), 0);.

🫶 Parameters 🫶

• none — she takes no parameters, periodt 😌

💖 Return value 💖

Iterator to the first element. That's the whole point, and it ate 🔥.

🦋 Example 🦋

Reason: no example.

not me staring at the missing example like 👀 — the page really says no example, so we're not making one up, bestie.
