Errors surfaced while restoring a cache snapshot tail.

Variants

EventStore(EventStoreError)

The event-store reader failed.

SnapshotRestore

The caller-provided snapshot restore hook failed.

Fields

blob_ref: String

Cache-owned snapshot blob reference.

message: String

Error message returned by the restore hook.

UnexpectedSeq

The replay scan yielded an entry outside the derived restore bounds.

Fields

seq: u64

Entry sequence yielded by the scan.

from_seq: u64

First sequence this replay is allowed to apply.

Decode

A captured payload failed to decode.

Fields

seq: u64

Event-store sequence number.

payload_type: String

Captured payload type tag.

message: String

Decode error message.

Apply

Applying a decoded payload to the cache failed.

Fields

seq: u64

Event-store sequence number.

payload_type: String

Captured payload type tag.

message: String

Apply error message.

Implementations

impl CacheReplayError

pub fn snapshot_restore(anchor: &SnapshotAnchor, error: impl Display) -> Self

Builds a snapshot-restore error for anchor.

Trait Implementations

impl Debug for CacheReplayError

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

Formats the value using the given formatter.

impl Display for CacheReplayError

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

Formats the value using the given formatter.

impl Error for CacheReplayError

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<CacheReplayError> for KernelError

fn from(source: CacheReplayError) -> Self

Converts to this type from the input type.

impl From<EventStoreError> for CacheReplayError

fn from(source: EventStoreError) -> Self

Converts to this type from the input type.
