Returns aniterator or asentinel that compares equal to the end iterator of thezip_view.

Letviews_ denote the underlying tuple of views.

1) Equivalent to:

return/*sentinel*/<false>(/*tuple-transform*/(ranges::end, views_));,

if/*zip-is-common*/<Views...> evaluates tofalse. Otherwise,

return begin()+std::iter_difference_t</*iterator*/<false>>(size());,

if(ranges::random_access_range<Views>&& ...) evaluates totrue. Otherwise,

return/*iterator*/<false>(/*tuple-transform*/(ranges::end, views_));.

2) Equivalent to:

return/*sentinel*/<true>(/*tuple-transform*/(ranges::end, views_));,

if/*zip-is-common*/<const Views...> evaluates tofalse. Otherwise,

return begin()+std::iter_difference_t</*iterator*/<true>>(size());,

ifranges::random_access_range<const Views>&& ... evaluates totrue. Otherwise,

return/*iterator*/<true>(/*tuple-transform*/(ranges::end, views_));.

[edit]Parameters

(none)

[edit]Return value

An iterator or sentinel representing the end of thezip_view, as described above.

[edit]Notes

ranges::range<constranges::zip_view<Views...>> is modeled if and only if for every typeVi inViews...,const Vi modelsrange.
