Performs iterator arithmetic or calculates the distance.

Let current_ denote the underlying tuple of iterators and parent_ denote the underlying pointer to cartesian_product_view.

1) Equivalent to: return /*iterator*/(i) += n;.

2) Equivalent to: return i + n;.

3) Equivalent to: return /*iterator*/(i) -= n;.

4) Equivalent to: return i.distance_from(j.current_);.

5) Let /*end-tuple*/ be an object of a type that is a specialization of tuple, such that:

• std::get<0>(/*end-tuple*/) has the same value as ranges::end(std::get<0>(i.parent_->bases_));
• std::get<N>(/*end-tuple*/) has the same value as ranges::begin(std::get<N>(i.parent_->bases_)) for every integer 1 ≤ N ≤ sizeof...(Vs).

Equivalent to: return i.distance_from(/*end-tuple*/);.

6) Equivalent to: return -(i - s);.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when cartesian_product_view::iterator<Const> is an associated class of the arguments.

Parameters

i, j	-	the iterators
n	-	the position relative to current location
s	-	the sentinel

Return value

1,2) An incremented iterator.

3) A decremented iterator.

4) A distance between given iterators.

5,6) A distance between given iterator and sentinel.
