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==
.
