friend constexpr bool operator== ( const /*iterator*/ & x, const /*iterator*/ & y )
    requires std::equality_comparable < /*ziperator*/ <Const>> ;
(1) (since C++23)
friend constexpr auto operator<=> ( const /*iterator*/ & x, const /*iterator*/ & y )

requires ranges::random_access_range <Base> &&

(2) (since C++23)

Compares the underlying iterators. Let inner_ denote the underlying iterator.

Equivalent to:

1) return x.inner_ == y.inner_;
2) return x.inner_ <=> y.inner_;

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::zip_transform_view::iterator<Const>

The <, <=, >, >=, and != operators are synthesized from operator<=> and operator==

Parameters

x, y - iterators to compare

Return value

The result of comparison
