Implementations

impl DesSaltPersistenceError

pub fn operation(&self) -> DesSaltPersistenceOperation

Return the failed transition.

pub fn previous_engine_boots(&self) -> Option<u32>

Return the last durable epoch, if this was a restart.

pub fn attempted_engine_boots(&self) -> u32

Return the epoch that the callback was asked to persist.

pub fn persistence_source(&self) -> &(dyn Error + Send + Sync + 'static)

Return the concrete persistence callback error.

pub fn downcast_source_ref<E: Error + 'static>(&self) -> Option<&E>

Downcast the callback error to its concrete type.

Trait Implementations

impl Debug for DesSaltPersistenceError

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

Formats the value using the given formatter.

impl Display for DesSaltPersistenceError

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

Formats the value using the given formatter.

impl Error for DesSaltPersistenceError

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.
