Errors raised while validating or evaluating deterministic rules.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyValue

A required rule identifier or explanation was empty.

Fields

field: &'static str

EmptyExpression

A logical group did not contain any child expression.

Fields

operator: &'static str

EmptyCalibrations

A hypothesis conclusion did not define any evidence calibration.

InvalidAggregationLimit

A bounded evidence aggregation requested zero contributions.

VerifierOnlyState

A rule attempted to assign a state reserved for a verifier.

Fields

state: HypothesisState

RuleIdentityConflict

A rule identity was reused with different semantics.

Fields

id: String

MissingCalibratedEvidence

A matched rule could not bind any contributing evidence.

Fields

rule_id: String

AmbiguousEvidenceCalibration

Two calibrations assigned different likelihoods to one observation.

Fields

rule_id: String

Rule containing the conflicting calibration.

evidence_id: EvidenceId

Evidence that matched more than one incompatible selector.

Ontology(OntologyError)

Ontology evaluation failed.

Reasoning(ReasoningModelError)

A reasoning-domain invariant failed.

Knowledge(KnowledgeBaseError)

A materialized hypothesis conflicted with stored knowledge.

StaleSnapshotRetriesExhausted

Concurrent rule-visible writes prevented a stable reasoning commit.

Fields

attempts: u8

Trait Implementations

impl Debug for RuleEngineError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RuleEngineError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl Error for RuleEngineError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
