These structs (a newtyped TyVid) are used as the unification key
for the eq_relations
; they carry a TypeVariableValue
along
with them.

If true, then self
should be preferred as root to other
. Note that we assume a consistent partial ordering, so returning true implies that other.prefer_as_root_to(self)
would return false. If there is no ordering between two keys (i.e., a.prefer_as_root_to(b)
and b.prefer_as_root_to(a)
both return false) then the rank will be used to determine the root in an optimal way. Read more
