friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y )
  requires std::is_reference_v<InnerBase> &&
           std::equality_comparable<ranges::iterator_t<Base>> &&
(since C++23)

Compares the underlying iterators. Two iterators are equal if their stored outer iterators and inner iterators are respectively equal.

The inner iterators may point into either InnerBase or PatternBase. They compare equal only if both point into InnerBase or both point into PatternBase, and in either case they have the same value.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::join_with_view::iterator<Const> is an associated class of the arguments.

The != operator is synthesized from operator==.


x, y - iterators to compare

Return value

result of comparison.
