> > Would it be enough to require that sizes[i] == 0 when i is null to call it a "valid empty list-view" > > At least in Rust the rule is that a slice must have an end index less than or equal to the length of the data being sliced. > > So in this case a slice would be valid iff `sizes[i] + offsets[i] <= child_data[0].length()`. > > It has been a while since I worked in C++, but if I recall correctly this is consistent with the way iterators work as well. I will rewrite the text saying that non-empty nulls are allowed, then. -- This is an automated message from the Apache Git Service.
