Variants

AddGoal(CanonicalState<'tcx, Goal<'tcx, Predicate<'tcx>>>)

We added a goal to the EvalCtxt which will get proven the next time EvalCtxt::try_evaluate_added_goals is called.

EvaluateGoals(AddedGoalsEvaluation<'tcx>)

The inside of a EvalCtxt::try_evaluate_added_goals call.

NestedProbe(Probe<'tcx>)

A call to probe while proving the current goal. This is used whenever there are multiple candidates to prove the current goalby .

Trait Implementations

impl<'tcx> PartialEq<ProbeStep<'tcx>> for ProbeStep<'tcx>

fn eq(&self, other: &ProbeStep<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> Eq for ProbeStep<'tcx>

impl<'tcx> StructuralEq for ProbeStep<'tcx>

impl<'tcx> StructuralPartialEq for ProbeStep<'tcx>

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.
