std::ranges::chunk_view<V>::end

V models only input_range 
constexpr std::default_sentinel_t end() const noexcept;
 (1) (since C++23)
V models forward_range 
constexpr auto end() requires (!__simple_view<V>);
 (2) (since C++23) 
constexpr auto end() const requires ranges::forward_range<const V>;
 (3) (since C++23)

Returns an iterator or a std::default_sentinel that compares equal to the end iterator of the chunk_view.

1) Available only if V models input_range. Equivalent to: return std::default_sentinel.
2-3) Available if V models forward_range. Let base_ denote the underlying adapted view, n_ denote the stored chunk size, and iterator denote the nested iterator class.
2) Equivalent to: 
if constexpr (ranges::common_range<V> && ranges::sized_range<V>)
{
    auto missing = (n_ - ranges::distance(base_) % n_) % n_;
    return iterator<false>(this, ranges::end(base_), missing);
}
else if constexpr (ranges::common_range<V> && !ranges::bidirectional_range<V>)
    return iterator<false>(this, ranges::end(base_));
else
    return std::default_sentinel;
3) Equivalent to: 
if constexpr (ranges::common_range<const V> && ranges::sized_range<const V>)
{
    auto missing = (n_ - ranges::distance(base_) % n_) % n_;
    return iterator<true>(this, ranges::end(base_), missing);
}
else if constexpr (ranges::common_range<const V> && !ranges::bidirectional_range<const V>)
    return iterator<true>(this, ranges::end(base_));
else
    return std::default_sentinel;

Parameters

(none).

Return value

An iterator or sentinel representing the end of the chunk_view, as described above.
