Variants§
AddGoal(GoalSource, 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 .
CommitIfOkStart
CommitIfOkSuccess

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
