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

okay so this is the std::ranges...view::begin(3) page from the C++ Standard Libary manual — yes, the title has the dots and the manual name has the typo, we are keeping both exactly as they are, no cap 💅✨

✨ NAME ✨

std::ranges::zip_view::begin — std::ranges::zip_view::begin (the name is literally the name, iconic behavior, we love a self-referential moment 🎀)

🌸 Synopsis 🌸

bestie, here’s the signature tea, copied exactly:

          constexpr auto begin()                            (1) (since C++23)
              requires (!(/*simple-view*/<Views> && ...));
          constexpr auto begin() const                      (2) (since C++23)
              requires (ranges::range<const Views> && ...);

This one obtains the beginning iterator of zip_view. periodt 🦋

1. Equivalent to return /*iterator*/<false>(/*tuple-transform*/(ranges::begin, views_));.
2. Equivalent to return /*iterator*/<true>(/*tuple-transform*/(ranges::begin, views_));.

🎀 Parameters 🎀

(none) — not a single parameter, she’s low-maintenance like that 💖

🌈 Return value 🌈

Iterator to the first element. that’s the whole vibe 🔥

💜 Notes 💜

ranges::range<const ranges::zip_view<Views...>> is modeled if and only if for every type Vi in Views..., const Vi models range. that “if and only if” is doing main character work, don’t skip it 👑

🧚 Example 🧚

no example yet, bestie, the page said what it said 😭🙈
