Variants

AddGoal(Canonical<'tcx, State<'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 .
