std::ranges::zip_view<Views...>::end

(1) | (since C++23) |
|
(2) | (since C++23) |
|
(3) | (exposition only*) |
Returns a sentinel or an iterator that compares equal to the end iterator of the std::zip_view.
Let views_ denote the underlying tuple of views.
return /*sentinel*/<false>(/*tuple-transform*/(ranges::end, views_));,
/*zip-is-common*/<Views...> evaluates to false. Otherwise,
return begin() + std::iter_difference_t</*iterator*/<false>>(size());,
(ranges::random_access_range<Views> && ...) evaluates to true. Otherwise,
return /*iterator*/<false>(/*tuple-transform*/(ranges::end, views_));.
return /*sentinel*/<true>(/*tuple-transform*/(ranges::end, views_));,
/*zip-is-common*/<const Views...> evaluates to false. Otherwise,
return begin() + std::iter_difference_t</*iterator*/<true>>(size());,
ranges::random_access_range<const Views> && ... evaluates to true. Otherwise,
return /*iterator*/<true>(/*tuple-transform*/(ranges::end, views_));.
Parameters
(none)
Return value
An iterator or sentinel representing the end of the zip_view, as described above.
Notes
ranges::range<const ranges::zip_view<Views...>> is modeled if and only if for every type Vi in Views..., const Vi models range.
