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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
