Function rustc_borrowck::universal_regions::for_each_late_bound_region_in_recursive_scope

fn for_each_late_bound_region_in_recursive_scope<'tcx>(
    tcx: TyCtxt<'tcx>,
    mir_def_id: LocalDefId,
    f: impl FnMut(Region<'tcx>),
)

Iterates over the late-bound regions defined on mir_def_id and all of its parents, up to the typeck root, and invokes f with the liberated form of each one.
