> Currently the "struct_field" kernel only works for integer indices for the
> child fields. From the StructFieldOption class
> (https://github.com/apache/arrow/blob/3d7f2f22a0fc441a41b8fa971e11c0f4290ebb24/cpp/src/arrow/compute/api_scalar.h#L283-L285):
> {code}
> /// The child indices to extract. For instance, to get the 2nd child
> /// of the 1st child of a struct or union, this would be {0, 1}.
> std::vector<int> indices;
> {code}
> It would be nice if you could also refer to fields by name in addition to by
> position.
