EvalCtxt
ExternalConstraintsData: Additional constraints returned on success.
FulfillmentCtxt: A trait engine using the new trait solver.
Goal: A goal is a statement, i.e. predicate, we want to prove given some assumptions, i.e. param_env.
GoalEvaluation: The result of evaluating a goal.
GoalStalledOn: The conditions that must change for a goal to warrant
NestedNormalizationGoals
NoSolution
QueryInput
Response
StalledOnCoroutines: Detect if a goal is stalled on a coroutine that is owned by the current typeck root.

AdtDestructorKind: Indicates that a impl Drop for Adt is const or not.
AliasBoundKind
BuiltinImplSource
CandidatePreferenceMode: Which trait candidates should be preferred over other candidates? By default, prefer where bounds over alias bounds. For marker traits, prefer alias bounds over where bounds.
CandidateSource: Possible ways the given goal can be proven.
Certainty
GenerateProofTree
GoalSource: Why a specific goal has to be proven.
HasChanged: Whether evaluating this goal ended up changing the inference state.
MaybeCause: Why we failed to evaluate a goal.
NextSolverError
OpaqueTypesJank: Supporting not-yet-defined opaque types in HIR typeck is somewhat challenging. Ideally we’d normalize them to a new inference variable and just defer type inference which relies on the opaque until we’ve constrained the hidden type.
ParamEnvSource
SizedTraitKind: Which sizedness trait - Sized, MetaSized? PointeeSized is omitted as it is removed during lowering.

deeply_normalize: Deeply normalize all aliases in value. This does not handle inference and expects its input to be already fully resolved.
deeply_normalize_with_skipped_universes: Deeply normalize all aliases in value. This does not handle inference and expects its input to be already fully resolved.
deeply_normalize_with_skipped_universes_and_ambiguous_coroutine_goals: Deeply normalize all aliases in value. This does not handle inference and expects its input to be already fully resolved.
evaluate_root_goal_for_proof_tree_raw 🔒
evaluate_root_goal_for_proof_tree_raw_provider: Do not call this directly, use the tcx query instead.
