constexpr auto end() requires (!__SimpleView<V>);
(1) (since C++23)
constexpr auto end() const requires ranges::range<const V>;
(2) (since C++23)

Returns an iterator or a sentinel representing the end of the adjacent_view.

Let base_ be the underlying view.

1) Equivalent to:
if constexpr (ranges::common_range<V>)
    return /*iterator*/<false>(__as_sentinel{}, ranges::begin(base_), ranges::end(base_));
else
    return /*sentinel*/<false>(ranges::end(base_));
2) Equivalent to:
if constexpr (ranges::common_range<const V>)
    return /*iterator*/<true>(__as_sentinel{}, ranges::begin(base_), ranges::end(base_));
else
    return /*sentinel*/<true>(ranges::end(base_));

[edit] Parameters

(none)

[edit] Return value

An iterator to the element following the last element, if the underlying view V models common_range. Otherwise, a sentinel which compares equal to the end iterator.

[edit] Notes

ranges::adjacent_view<V,N> models common_range whenever the underlying view V does.
