Compares the underlying iterators: inner_.

1) Equivalent to return x.inner_ == y.inner_;
2) Equivalent to return x.inner_ < y.inner_;
3) Equivalent to return x.inner_ > y.inner_;
4) Equivalent to return x.inner_ <= y.inner_;
5) Equivalent to return x.inner_ >= y.inner_;
6) Equivalent to 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::adjacent_transform_view::iterator<Const>

The != operator is synthesized from operator==.

Parameters

x, y - iterators to compare

Return value

Result of comparison.
