Error during a direct or guarded batch.

Variants

EmptyBatch

The batch contained no write operations.

InvalidCommitTimestamp

The commit timestamp is less than or equal to a guard’s read timestamp.

Fields

read_ts: Timestamp

The read timestamp of the guard.

commit_ts: Timestamp

The invalid commit timestamp.

CommitTsTooOld

The commit timestamp is older than the latest committed version for a key.

Fields

key: Vec<u8>

The key that caused the error.

commit_ts: Timestamp

The requested commit timestamp.

latest_commit_ts: Timestamp

The latest committed version’s timestamp.

NoReadGuards

A guarded batch was submitted without any read guards.

DuplicateKeyInBatch

The batch contains multiple physical writes for the same key.

Fields

key: Vec<u8>

The duplicate key.

KeyLocked

A key in the batch is currently locked by an active intent.

Fields

key: Vec<u8>

The locked key.

txn_id: TxnId

The transaction ID holding the lock.

GuardFailedNewerVersion

A read guard failed because a newer version exists after the read_ts.

Fields

key: Vec<u8>

The key that failed the guard.

read_ts: Timestamp

The read timestamp of the guard.

actual_commit_ts: Timestamp

The timestamp of the newer version.

GuardFailedVersionMismatch

A read guard failed because the actual version did not match the expected version.

Fields

key: Vec<u8>

The key that failed the guard.

expected: Option<Timestamp>

The expected commit timestamp (or None if expected absent).

actual: Option<Timestamp>

The actual commit timestamp found (or None if actually absent).

GuardFailedValueMismatch

A read guard failed because the actual logical value did not match the expected value.

Fields

key: Vec<u8>

The key that failed the guard.

Backend(String)

An error returned by the backend storage.

Trait Implementations

impl Clone for BatchError

fn clone(&self) -> BatchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchError

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

Formats the value using the given formatter.

impl Display for BatchError

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

Formats the value using the given formatter.

impl Eq for BatchError

impl Error for BatchError

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 BatchError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
