friend constexpr bool operator==( const /*iterator*/& x, const /*iterator*/& y )

    requires
        /*ref-is-glvalue*/ &&
        std::equality_comparable<ranges::iterator_t<Base>> &&

        std::equality_comparable<ranges::iterator_t<ranges::range_reference_t<Base>>>;
(since C++20)

Compares the underlying iterators.

Equivalent to: return (x.outer_ == y.outer_) and (x.inner_ == y.inner_);, where outer_ and inner_ are the underlying iterators. The constant /*ref-is-glvalue*/ in the requires-clause is equal to std::is_reference_v<ranges::range_reference_t<Base>>.

The != operator is synthesized from operator==.

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