Compares the underlying iterators (or the underlying iterator and the default sentinel (2)).
Let current_ and end_ be the underlying data members.
Equivalent to:
return x.current_ == y.current_;.return x.current_ == x.end_;.return x.current_ < y.current_;.return y < x;.return !(y < x);.return !(x < y);.return x.current_ <=> y.current_;.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::ranges::chunk_view::iterator<Const> is an associated class of the arguments.
The != operator is synthesized from operator==.
| x, y | - | the iterators to compare |
The result of comparison.
