Function rustc_query_impl::make_query::predicates_defined_on

pub fn predicates_defined_on<'tcx>(

    key: predicates_defined_on<'tcx>
) -> QueryStackFrame

Maps from the DefId of an item (trait/struct/enum/fn) to the predicates (where-clauses) directly defined on it. This is equal to the explicit_predicates_of predicates plus the inferred_outlives_of predicates.
