std::ranges::cartesian_product_view<First, Vs...>::iterator
|
(since C++23) (exposition only*) |
The return type of cartesian_product_view::begin, and of cartesian_product_view::end when the underlying view V is a common_range.
The type /*iterator*/<true> is returned by the const-qualified overloads. The type /*iterator*/<false> is returned by the non-const-qualified overloads.

difference_type |
An implementation-defined signed-integer-like type (maybe the smallest of such types), which is sufficiently wide to store the product of the maximum sizes of all underlying ranges, if such type exists. |

Data members

parent_ (private) |
A pointer of type Parent to the parent cartesian_product_view.(exposition-only member object*) |

Member functions
|
(C++23)
|
constructs an iterator (public member function) |
|
(C++23)
|
accesses the element (public member function) |
|
(C++23)
|
accesses an element by index (public member function) |
|
(C++23)
|
advances or decrements the underlying iterator (public member function) |
|
(C++23)
|
advances the iterator (exposition-only member function*) |
|
(C++23)
|
decrements the iterator (exposition-only member function*) |
|
(C++23)

Non-member functions
|
(C++23)

|
(C++23)
|
swaps underlying pointed-to elements (function) |
