As a follow-up, I didn't notice this during my initial review, but in
testing this line was throwing attribute errors for me due to Topology
not having an attribute named `type`. I think this was because of
`Topology.type.no_link` since this attribute isn't initialized on the
class itself. I fixed this by just replacing it with
`TopologyType.no_link` locally.
