Struct rustc_middle::traits::DerivedObligationCause
source · pub struct DerivedObligationCause<'tcx> {
pub parent_trait_pred: PolyTraitPredicate<'tcx>,
pub parent_code: InternedObligationCauseCode<'tcx>,
}
Fields
parent_trait_pred: PolyTraitPredicate<'tcx>
The trait predicate 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 predicate here directly.
parent_code: InternedObligationCauseCode<'tcx>
The parent trait had this cause.

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
