constexpr auto begin() const
requires (ranges::range<const Views> && ...);
| (2) | (since C++23) |
Obtains the beginning iterator of zip_view.
return /*iterator*/<false>(/*tuple-transform*/(ranges::begin, views_));.return /*iterator*/<true>(/*tuple-transform*/(ranges::begin, views_));.(none).
Iterator to the first element.
ranges::range<const ranges::zip_view<Views...>> is modeled if and only if for every type Vi in Views..., const Vi models range.

(C++23) | returns an iterator or a sentinel to the end (public member function) |
|
(C++20) | returns an iterator to the beginning of a range (customization point object) |
