Error during a prewrite batch.

Variants

EmptyBatch

The batch contained no write operations.

DuplicateKeyInBatch

The batch contains multiple writes for the same key.

Fields

key: Vec<u8>

The duplicate key.

KeyLocked

A key in the batch is currently locked by another active transaction.

Fields

key: Vec<u8>

The locked key.

txn_id: TxnId

The transaction ID holding the lock.

WriteConflict

A committed version exists that is newer than the transaction’s start_ts.

Fields

key: Vec<u8>

The key that caused the conflict.

IntentAlreadyExists

An intent already exists for the same transaction but with different parameters.

Fields

key: Vec<u8>

The key with the conflicting intent.

PartialBatchReplay

The batch is a partial replay, meaning some intents exist while others do not.

Backend(String)

An error returned by the backend storage.

impl Eq for BatchPrewriteError

impl Error for BatchPrewriteError

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.
