class /*iterator*/
(since C++23)
(exposition only*)

The return type of chunk_view::begin, and of chunk_view::end when the underlying view V is a common_range.

Present only if V models forward_range.

The type /*iterator*/<true> is returned by the const-qualified overloads. The type /*iterator*/<false> is returned by the non-const-qualified overloads.

[edit] Data members

Member name Definition
current_ (private) ranges::iterator_t<Base>, holds an iterator to the first element of current chunk in the underlying sequence (i.e. the begin of a chunk).
(exposition-only member object*)
end_ (private) ranges::sentinel_t<Base>, holds a sentinel to the end of the underlying sequence.
(exposition-only member object*)
n_ (private) ranges::range_difference_t<Base>, holds initial number of elements in the chunk (the last chunk can be smaller).
(exposition-only member object*)
missing_ (private) ranges::range_difference_t<Base>, usually equals to ranges::advance(current_, n_, end_);.
(exposition-only member object*)
