std::ranges::chunk_view
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.
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 ;
[edit] Return value
An iterator or sentinel representing the end of the chunk_view, as described above.
