constexpr auto end() requires (!__simple_view<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 stride_view.

Let base_ and stride_ be the underlying data members.

1) Let Const be defined as using Const = false; and Base as using Base = V;.
2) Let Const be defined as using Const = true; and Base as using Base = const V;.

Equivalent to:

if constexpr (ranges::common_range<Base> &&
              ranges::sized_range<Base> &&
              ranges::forward_range<Base>)
{
    auto missing = (stride_ - ranges::distance(base_) % stride_) % stride_;
    return iterator<Const>(this, ranges::end(base_), missing);
}
else if constexpr (ranges::common_range<Base> &&
                   !ranges::bidirectional_range<Base>)
{
    return iterator<Const>(this, ranges::end(base_));
}
else
{
    return std::default_sentinel;
}

[edit] Parameters

(none)

[edit] Return value

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

[edit] Notes

stride_view<V> models common_range whenever the underlying view V does.
