Function rustc_trait_selection::traits::astconv_object_safety_violations

pub fn astconv_object_safety_violations(
    tcx: TyCtxt<'_>, 
    trait_def_id: DefId
) -> Vec<ObjectSafetyViolation>

Returns the object safety violations that affect astconv -- currently, Self in supertraits. This is needed because object_safety_violations can't be used during type collection.
