Enum EventLogError 

#[non_exhaustive]
pub enum EventLogError {
    Journal(Error),
    Checkpoint(Error),
    Integrity(IntegrityError),
}

Failures from opening, appending to, or replaying an crate::EventLog.

This is a thin wrapper over the underlying commonware_storage::journal::Error: every fallible event-log operation delegates to the journal primitive, so the storage error is the only failure mode and is preserved verbatim as the Self::Journal source.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Journal(Error)

The underlying commonware-storage journal returned an error while opening, appending, committing, or replaying.

Checkpoint(Error)

The durable event-count checkpoint (crate::checkpoint) failed to open, read, or sync.

Integrity(IntegrityError)

A partition’s tamper-evidence tree could not be rebuilt, or its root could not be signed.

A rewrite reports this rather than proceeding: every root the partition carried was signed over content the rewrite changes, so a rewrite that cannot sign a fresh one would leave a partition whose signed history does not describe what it holds.

Trait Implementations

impl Debug for EventLogError

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

Formats the value using the given formatter.

impl Display for EventLogError

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

impl Error for EventLogError

fn source(&self) -> Option<&(dyn Error + 'static)>

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
