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

template<bool Const>
class /*sentinel*/; // exposition only
(since C++20)

The return type of take_while_view::end.

The type /*sentinel*/<true> is returned by the const-qualified overload. The type /*sentinel*/<false> is returned by the non-const-qualified overload.

The name of this class template (shown here as sentinel) is unspecified.

Typical implementation holds two data members: a sentinel that represents the end of the underlying view, and a pointer to the predicate.
