ranges::range <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).
[edit] Parameters
(none)
[edit] Return value
A sentinel representing the end of the view.
