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