std::ranges::adjacent_transform_view<V,F,N>::end

constexpr auto end();
 (1) (since C++23) 
constexpr auto end() const
    requires ranges::range<const InnerView> &&
        std::regular_invocable<const F&,
            __REPEAT(ranges::range_reference_t<const V>, N)...>;
 (2) (since C++23)

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

Let inner_ be the underlying ranges::adjacent_view.

1) Equivalent to: 
if constexpr (ranges::common_range<InnerView>)
    return /*iterator*/<false>(*this, inner_.end());
else
    return /*sentinel*/<false>(inner_.end());
2) Equivalent to: 
if constexpr (ranges::common_range<const InnerView>)
    return /*iterator*/<true>(*this, inner_.end());
else
    return /*sentinel*/<true>(inner_.end());

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

adjacent_transform_view<V,F,N> models common_range whenever the underlying view V does.
