}

Fields

parent_trait_ref: Binder<TraitRef<'tcx>>

The trait reference of the parent obligation that led to the current obligation. Note that only trait obligations lead to derived obligations, so we just store the trait reference here directly.

parent_code: Rc<ObligationCauseCode<'tcx>>

The parent trait had this cause.
