Compares the underlying iterators: inner_.
return x.inner_ == y.inner_;.return x.inner_ < y.inner_;.return x.inner_ > y.inner_;.return x.inner_ <= y.inner_;.return x.inner_ >= y.inner_;.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> is an associated class of the arguments.
The != operator is synthesized from operator==.
