Variants

`ConcreteFailure(SubregionOrigin<'tcx>, &'tcx RegionKind, &'tcx RegionKind)`

ConcreteFailure(o, a, b):

o requires that a <= b, but this does not hold

`GenericBoundFailure(SubregionOrigin<'tcx>, GenericKind<'tcx>, &'tcx RegionKind)`

`GenericBoundFailure(p, s, a)

The parameter/associated-type p must be known to outlive the lifetime a (but none of the known bounds are sufficient).

`SubSupConflict(RegionVid, RegionVariableOrigin, SubregionOrigin<'tcx>, &'tcx RegionKind, SubregionOrigin<'tcx>, &'tcx RegionKind, Vec<Span, Global>)`

SubSupConflict(v, v_origin, sub_origin, sub_r, sup_origin, sup_r):

Could not infer a value for v (which has origin v_origin) because sub_r <= v (due to sub_origin) but v <= sup_r (due to sup_origin) and sub_r <= sup_r does not hold.

`UpperBoundUniverseConflict(RegionVid, RegionVariableOrigin, UniverseIndex, SubregionOrigin<'tcx>, &'tcx RegionKind)`

Indicates a 'b: 'a constraint where 'a is in a universe that cannot name the placeholder 'b.
