friend constexpr bool operator== ( const /*iterator*/ & x, std::default_sentinel_t ) ;	(2)	(since C++23)

Compares two iterators or an iterator and a sentinel.

Let current_ denote the underlying tuple of iterators.

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>

The != operator is synthesized from operator==.

Parameters

x, y

-

iterators or sentinels to compare

Return value

The result of comparison.
