Struct rustc_trait_selection::solve::inspect::InspectCandidate

pub struct InspectCandidate<'a, 'tcx> {
    goal: &'a InspectGoal<'a, 'tcx>,
    kind: ProbeKind<'tcx>,
    nested_goals: Vec<CanonicalState<'tcx, Goal<'tcx, Predicate<'tcx>>>>,
    result: QueryResult<'tcx>,
}

Fields

goal: &'a InspectGoal<'a, 'tcx>

kind: ProbeKind<'tcx>

nested_goals: Vec<CanonicalState<'tcx, Goal<'tcx, Predicate<'tcx>>>>

result: QueryResult<'tcx>

Implementations

impl<'a, 'tcx> InspectCandidate<'a, 'tcx>

pub fn infcx(&self) -> &'a InferCtxt<'tcx>

pub fn kind(&self) -> ProbeKind<'tcx>

pub fn result(&self) -> Result<Certainty, NoSolution>

pub fn visit_nested<V: ProofTreeVisitor<'tcx>>( &self, visitor: &mut V ) -> ControlFlow<V::BreakTy>

Visit the nested goals of this candidate.

FIXME(@lcnr): we have to slightly adapt this API to also use it to compute the most relevant goal for fulfillment errors. Will do that once we actually need it.

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.
