Errors that can occur during journal replay.

Variants

Journal(JournalError)

Error reading from the journal.

Reduce(ReduceError)

Reducer returned an error.

MissingRunMeta

First event is not RunMeta (required by §9.2).

IncompleteRunMeta(&'static str)

RunMeta event is present but missing required fields.

UnsupportedSchema(u16)

Journal schema version is not supported.

CheckpointHashMismatch

Checkpoint state hash does not match replayed state.

Fields

expected: String

got: String

CheckpointRunIdMismatch

Checkpoint run_id does not match journal RunMeta run_id.

Fields

expected: Uuid

got: Uuid

SeqGap

Non-contiguous sequence number during replay.

Fields

expected: u64

got: u64

DuplicateEventId(Uuid)

Duplicate event_id during replay.

RunIdMismatch

Event run_id does not match the run_id established by RunMeta.

Fields

seq: u64

expected: Uuid

got: Uuid

CheckpointNotReached

Checkpoint boundary was never reached in the event stream.

Fields

up_to_seq: u64

last_seq: u64

HashChainVerificationRequiresFileReplay

Hash-chain verification requires file-based replay where encoding is known.

Trait Implementations

impl Debug for ReplayError

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

Formats the value using the given formatter.

impl Display for ReplayError

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

Formats the value using the given formatter.

impl Error for ReplayError

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 From<JournalError> for ReplayError

fn from(source: JournalError) -> Self

Converts to this type from the input type.

impl From<ReduceError> for ReplayError

fn from(source: ReduceError) -> Self

Converts to this type from the input type.
