Errors from RuntimeStore operations.

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.

WriteFailed(String)

Write failed.

ReadFailed(String)

Read failed.

SessionKeyMismatch

The explicit session-store key does not match the serialized session.

Fields

expected: SessionId

actual: SessionId

NotFound(String)

Not found.

Unsupported(String)

Operation is not supported by this store implementation.

OpsLifecycleEpochRetired

A detached producer attempted to persist an ops snapshot after the matching epoch was atomically retired by unregister.

Fields

runtime_id: String

epoch_id: RuntimeEpochId

UnregisterFinalizationOutcomeUnknown(String)

An unregister-finalization commit may have become durable, but the backend could not authoritatively classify its outcome.

Callers must retry the idempotent atomic finalization and must not publish a compensating lifecycle rollback for this error.

TranscriptRevisionConflict

Runtime snapshot CAS rejected a stale transcript rewrite.

Fields

expected: String

actual: String

SessionSnapshotSuperseded

An atomic boundary commit carried a session snapshot that was already superseded by the durable append-only head. Callers must observe this as a failed commit rather than mistaking a no-op for publication.

Fields

runtime_id: String

InvalidInputStateBatchCas

The requested exact input-state batch CAS has an invalid row/key shape.

Fields

reason: String

MachineLifecycleRepairBlocked

A lifecycle record was observed exactly, but replacing it would risk lowering or fabricating durable runtime fencing authority.

This is a permanent reconciliation result for the observed row, not a transport retry. Callers should project RepairBlocked while retaining the evidence digest for operator repair.

Fields

evidence_digest: Option<String>

detail: String

SchemaFromTheFuture

The file’s schema ledger records a version newer than this binary supports: a newer binary migrated the file and this one must refuse it (typed, health-visible refusal — never a crash loop).

Fields

domain: String

found: i64

supported: i64

MaintenanceFenceHeld

The exclusive maintenance fence is held for this database; storage is under offline maintenance.

Fields

path: String

Internal(String)

Internal error.

Trait Implementations

impl Clone for RuntimeStoreError

fn clone(&self) -> RuntimeStoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeStoreError

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

Formats the value using the given formatter.

impl Display for RuntimeStoreError

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

Formats the value using the given formatter.

impl Error for RuntimeStoreError

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.
