friend constexpr bool

Compares the underlying iterators. Let pos_

1) Equivalent to return x.pos_ == y.pos_;
2) Equivalent to return x.pos_ <=> y.pos_;

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

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

Parameters

x, y - iterators to compare

Return value

Result of comparison.
