Struct rustc_infer::traits::DerivedObligationCause [−][src]
pub struct DerivedObligationCause<'tcx> {
pub parent_trait_ref: Binder<'tcx, TraitRef<'tcx>>,
pub parent_code: Rc<ObligationCauseCode<'tcx>>,
}
Fields
parent_trait_ref: Binder<'tcx, 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.

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