Struct CompleteAnswer

Source

pub struct CompleteAnswer<I: Interner> {
    pub subst: Canonical<ConstrainedSubst<I>>,
    pub ambiguous: bool,
}

Fields§

§subst: Canonical<ConstrainedSubst>

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: bool

If 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 }).
