§

AddGoal(GoalSource, Canonical<TyCtxt<'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 .

§

MakeCanonicalResponse

A call to EvalCtxt::evaluate_added_goals_make_canonical_response with Certainty was made. This is the certainty passed in, so it’s not unified with the certainty of the try_evaluate_added_goals that is done within; if it’s Certainty::Yes, then we can trust that the candidate is “finished” and we didn’t force ambiguity for some reason.
