Enum rustc_type_ir::solve::inspect::ProbeStep

AddGoal(GoalSource, CanonicalState<I, Goal<I, I::Predicate>>),

Variants§
AddGoal(GoalSource, CanonicalState<I, Goal<I, I::Predicate>>)
We added a goal to the EvalCtxt
which will get proven
the next time EvalCtxt::try_evaluate_added_goals
is called.
NestedProbe(Probe<I>)
A call to probe
while proving the current goal. This is
used whenever there are multiple candidates to prove the
current goal.
RecordImplArgs
A trait goal was satisfied by an impl candidate.
Fields
impl_args: CanonicalState<I, I::GenericArgs>
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.

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
