Struct chalk_engine::CompleteAnswer
source · [−]pub struct CompleteAnswer<I: Interner> {
pub subst: Canonical<ConstrainedSubst<I>>,
pub ambiguous: bool,
}Fields
subst: Canonical<ConstrainedSubst<I>>Contains values for the unbound inference variables for which the table is true, along with any region constrained (which must still be proven, but not by chalk).
ambiguous: boolIf this flag is set, then the answer could be neither proven
nor disproven. This could be the size of the answer exceeded
max_size or because of a negative loop (e.g., P :- not { P }).
