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

Compares two iterators or an iterator and a sentinel.

Let current_ denote the underlying tuple of iterators.

1) Equivalent to: return x.current_ == y.current_;

2) Returns true if std::get<i>(x.current_) == ranges::end(std::get<i>(x.parent_->bases_)) is true for any integer 0 ≤ i ≤ sizeof...(Vs). Otherwise, returns false.

3) Equivalent to: return x.current_ <=> y.current_;

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

The != operator is synthesized from operator==.

Parameters

x, y

-

iterators to compare

Return value

The result of comparison.
