constexpr auto begin() const
    requires (ranges::range<const Views> && ...);
(2) (since C++23)

Obtains the beginning iterator of zip_view.

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

Parameters

(none).

Return value

Iterator to the first element.

Notes

ranges::range<const ranges::zip_view<Views...>> is modeled if and only if for every type Vi in Views..., const Vi models range.
