Fields§

§re_static: Region<'tcx>

ReStatic

§re_erased: Region<'tcx>

Erased region, used outside of type inference.

§re_vars: Vec<Region<'tcx>>

§re_late_bounds: Vec<Vec<Region<'tcx>>>

Pre-interned values of the form: ReLateBound(DebruijnIndex(i), BoundRegion { var: v, kind: BrAnon }) for small values of i and v.
