Variants

IllegalTransition

Fields

from: AttemptState

to: AttemptState

Workspace(WorkspaceError)

A stored workspace kind and slot that cannot describe one allocation, so the legal cleanup algorithm for the journalled path is undecidable.

BusyCannotBeCleaned

OutcomeUnreachable

Fields

from: AttemptState

outcome: AttemptOutcome

TerminalWithoutOutcome

Fields

state: AttemptState

NonTerminalWithOutcome

Fields

state: AttemptState

outcome: AttemptOutcome

OutcomeStateMismatch

Fields

state: AttemptState

outcome: AttemptOutcome

TerminalWithoutTimestamp

Fields

state: AttemptState

NonTerminalWithTimestamp

Fields

state: AttemptState

TimestampsOutOfOrder

Fields

state: AttemptState

field: &'static str

Which of the two orderable timestamps is out of order.

created_at: Timestamp

found: Timestamp

Trait Implementations

impl Eq for AttemptError

impl Error for AttemptError

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
