NAME¶

std::ranges::stride_view::end - std::ranges::stride_view::end

Synopsis¶

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;
}

Parameters¶

(none)

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.

Notes¶

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