Not currently. Work is being planned on this but it is more involved 
than it appears on the surface.

As of now it's recommended to just carry around the set of columns with 
you. You can also dig in the return of $rs->_resolved_attrs, HOWEVER 
THIS IS UNSUPPORTED AND *WILL* CHANGE without a warning. So make sure to 
write sufficient tests if yoiu go this route.
