Enum PrewriteError 

pub enum PrewriteError {
    KeyLocked {
        txn_id: TxnId,
    },
    WriteConflict,
    Backend(String),
    IntentAlreadyExists,
}

Error during a single-key prewrite operation.

Variants

KeyLocked

The key is locked by another active transaction.

Fields

txn_id: TxnId

The transaction ID currently holding the lock.

WriteConflict

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

Backend(String)

An error returned by the backend storage.

IntentAlreadyExists

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

Trait Implementations

impl Clone for PrewriteError

fn clone(&self) -> PrewriteError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrewriteError

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

Formats the value using the given formatter.

impl Display for PrewriteError

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

Formats the value using the given formatter.

impl Eq for PrewriteError

impl Error for PrewriteError

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 PrewriteError

fn eq(&self, other: &PrewriteError) -> 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.
