std::ranges::adjacent_view<V,N>:: end

From cppreference.com
Ranges library
Range adaptors
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_));

Parameters

(none)

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.

Notes

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