Compares the underlying iterators. Let current_ be an underlying array of iterators.

1) Equivalent to return x.current_.back() == y.current_.back().
2) Equivalent to return x.current_.back() < y.current_.back().
3) Equivalent to return y < x;.
4) Equivalent to return !(y < x);.
5) Equivalent to return !(x < y);.
6) Equivalent to return x.base() <=> y.base();.

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

The != operator is synthesized from operator==.

[edit] Parameters

x, y - iterators to compare

[edit] Return value

Result of comparison.
