std::ranges::take_while_view<V,Pred>::end
From cppreference.com
< cpp | ranges | take while view
constexpr auto end() requires (!/*simple-view*/<V>); |
(1) | (since C++20) |
constexpr auto end() const requires ranges::range<const V> && |
(2) | (since C++20) |
Returns a sentinel representing the end of the view.
Let base_
denote the underlying view.
1) Effectively returns /*sentinel*/<false>(ranges::end(base_), std::addressof(pred())).
2) Effectively returns /*sentinel*/<true>(ranges::end(base_), std::addressof(pred())).
Overload (1) does not participate in overload resolution if V
is a simple view (that is, if V
and const V are views with the same iterator and sentinel types).
