std::ranges::take_while_view<V,Pred>:: end

constexpr auto end ( ) requires ( ! /*simple-view*/ < V > ) ;	(1)	(since C++20)
constexpr auto end ( ) const requires ranges:: range < const V > && std:: indirect_unary_predicate < const Pred, ranges:: iterator_t < const V >> ;	(2)	(since C++20)

Returns a sentinel representing the end of the view.

Let base_ denote the underlying view.

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.
