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==
.
