std::ranges::chunk_view<V>::iterator<Const>::iterator

/*iterator*/() = default;
 (1) (since C++23) 
constexpr /*iterator*/( /*iterator*/<!Const> i )
    requires
        Const and
        std::convertible_to<ranges::iterator_t<V>, ranges::iterator_t<Base>> and
        std::convertible_to<ranges::sentinel_t<V>, ranges::sentinel_t<Base>>;
 (2) (since C++23) 
private:
constexpr /*iterator*/( Parent* parent,
                        ranges::iterator_t<Base> current,
                        ranges::range_difference_t<Base> missing = 0 );
 (3) (exposition only*)

Construct an iterator.

1) Default constructor. Value-initializes the underlying data members: 2) Conversion from /*iterator*/<false> to /*iterator*/<true>. Initializes the underlying data members:
  • current_ with std::move(i.current_),
  • end_ with std::move(i.end_),
  • n_ with i.n_,
  • missing_ with i.missing_.
3) A private constructor which is used by ranges::chunk_view::begin and ranges::chunk_view::end. This constructor is not accessible to users. Initializes the underlying data members:
  • current_ with current,
  • end_ with ranges::end(parent->base_),
  • n_ with parent->n_,
  • missing_ with missing.

Parameters

i - an /*iterator*/<false>
parent - a pointer to owning chunk_view
current - an iterator to the begin of current chunk
missing - a difference between expected (n_) and actual size of current chunk
