Routing contract or deterministic reduction failure.

Variants

UnsupportedSchema(String)

A routing plan, receipt, or catalog carries an unsupported schema_version.

UnsupportedAlgorithm(String)

A routing plan carries an unsupported algorithm_version.

UnsupportedCatalog(String)

A model catalog carries an unsupported catalog_version.

EmptyIdentity

A routing identity field is empty when a non-empty value is required.

InvalidDescriptor(String)

A model descriptor failed validation (e.g. invalid digest, empty provider).

DescriptorDigest(String)

The BLAKE3 digest in a model descriptor does not match its payload.

EmptyCatalog

A model catalog was constructed with zero descriptors.

CatalogOrder

The model catalog descriptors are not strictly sorted by digest.

InvalidCandidate(String)

A routing candidate failed validation (e.g. empty profile, invalid digests).

CandidateDigest(String)

The routing candidate ID does not match the material digest.

EmptyCandidates

The routing candidate list is empty when at least one is required.

CandidateOrder

The routing candidates are not sorted in deterministic preference order.

DuplicateCandidate(String)

Two or more routing candidates share the same digest identity.

UnknownDescriptor(String)

A routing candidate references a descriptor ID absent from the catalog.

UnknownLockedCandidate(String)

The locked candidate ID in bindings does not match any candidate.

InvalidRequirements

Routing requirements failed validation (e.g. zero-valued budgets).

InvalidBinding(String)

A binding field is not a valid BLAKE3 hex digest.

CatalogBinding

The model catalog digest in bindings does not match the catalog’s canonical digest.

SelectionMismatch

The selections computed during plan validation disagree with the stored selections.

CostOverflow

A routing cost estimate overflowed u64.

Serialization

Serde serialization of a routing structure failed.

ReceiptBinding

The receipt’s binding fields do not match the plan’s binding values.

ReceiptAttempts

The receipt attempt count, order, or per-attempt outcomes violate invariants.

ReceiptOutcome

The receipt terminal outcome is inconsistent with the attempt sequence.

Trait Implementations

impl Clone for RoutingError

fn clone(&self) -> RoutingError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoutingError

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

impl Eq for RoutingError

impl Error for RoutingError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RoutingError

fn eq(&self, other: &RoutingError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
