NAME¶

std::ranges::take_while_view::end - std::ranges::take_while_view::end

Synopsis¶

constexpr auto end() requires (!__SimpleView<V>); (1) (since C++20)
constexpr auto end() const requires

ranges::range<const V> && (2) (since C++20)

std::indirect_unary_predicate<const Pred,
ranges::iterator_t<const V>>;

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).

Parameters¶

(none)

Return value¶

A sentinel representing the end of the view.
