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

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