fn order_roots(

a_value: &Self::Value,
b: Self,
b_value: &Self::Value
) -> Option<(Self, Self)>
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 moreimpl<'tcx> Copy for RegionVidKey<'tcx>

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
