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.

Duplicate

The transaction ID already exists.

Fields

id: TransactionId

Duplicate ID.

NotFound

No record has this ID.

Fields

id: TransactionId

Missing ID.

StateConflict

Compare-and-transition observed another state.

Fields

id: TransactionId

Transaction ID.

expected: TransactionState

Required current state.

actual: TransactionState

State actually observed.

Transition(TransitionError)

The requested state edge is invalid.

ApprovalBindingMismatch

A grant for another exact artifact was presented.

Fields

requested: TransactionId

Transaction the caller attempted to approve.

bound: TransactionId

Transaction actually covered by the grant.

MissingApproval

An approved state lacked its grant and therefore failed closed.

Fields

id: TransactionId

Affected transaction.

ApprovalExpired

Approval expired and the record was moved to Expired.

Fields

id: TransactionId

Affected transaction.

expired_at_unix_ms: u64

Exclusive grant expiry.

observed_at_unix_ms: u64

Time supplied to reservation.

NotReservable

Current state can never win a new reservation.

Fields

id: TransactionId

Affected transaction.

actual: TransactionState

State actually observed.

PersistentIo

Durable state-file or cross-process lock I/O failed.

Fields

operation: &'static str

Stable operation label.

kind: ErrorKind

Portable operating-system error category.

PersistentCorrupt

Durable state bytes failed structural, checksum, or lifecycle validation.

Fields

offset: u64

Byte offset at which validation failed.

reason: &'static str

Stable corruption reason.

PersistentLogLimit

The append-only durable log exceeded its configured byte bound.

Fields

observed: u64

Bytes the next durable state would require.

maximum: u64

Configured byte ceiling.

PersistentRecordLimit

Unique durable transaction count exceeded its configured bound.

Fields

observed: usize

Unique records the operation would retain.

maximum: usize

Configured record ceiling.

Poisoned

Another thread panicked while mutating the in-memory reference backend.

Trait Implementations

impl Eq for TransactionStoreError

impl Error for TransactionStoreError

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
