Fields§

§derived: DerivedObligationCause<'tcx>§impl_or_alias_def_id: DefId

The DefId of the impl that gave rise to the derived obligation. If the derived obligation arose from a trait alias, which conceptually has a synthetic impl, then this will be the DefId of that trait alias. Care should therefore be taken to handle that exceptional case where appropriate.

§impl_def_predicate_index: Option<usize>

The index of the derived predicate in the parent impl’s predicates.

§span: Span
