Enum ExecutionRetryError 

pub enum ExecutionRetryError {
    SystemObjectUnavailable {
        object_id: ObjectID,
        version: SequenceNumber,
    },
}

Signals that transaction execution should be retried later rather than committed. Unlike ExecutionError, the transaction that produced it is not committed: execution still runs to completion and produces effects, but the authority discards those effects and re-enqueues the transaction once the condition clears. An enum so more retry reasons can be added.

Variants

SystemObjectUnavailable

A system object the transaction needs to read had not yet been committed locally at the version this transaction requires. The transaction should be retried once that object reaches version. The object id and the version to wait for are enough for the authority to register the wait: the object’s initial shared version, needed to form the full key, is recovered from the epoch start config (which records every system object).

Fields

object_id: ObjectID

version: SequenceNumber

Trait Implementations

impl Clone for ExecutionRetryError

fn clone(&self) -> ExecutionRetryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionRetryError

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

Formats the value using the given formatter.

impl Display for ExecutionRetryError

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

Formats the value using the given formatter.

impl Error for ExecutionRetryError

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 ExecutionRetryError

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