Errors that can occur in per-core WAL operations.

Variants

Io(Error)

IO error during WAL operations.

Serialization(String)

Serialization error when writing entries.

Deserialization(String)

Deserialization error when reading entries.

ChecksumMismatch

CRC32 checksum mismatch.

Fields

core_id: usize

Core ID of the segment.

position: u64

Position of the corrupted record.

expected: u32

Expected CRC32 value.

actual: u32

Actual CRC32 value.

TornWrite

Torn write detected (partial record at end of WAL).

Fields

core_id: usize

Core ID of the segment.

position: u64

Position where torn write was detected.

reason: String

Description of the torn write.

Corrupted

Fields

core_id: usize

Core ID of the segment.

position: u64

Position of the corrupted record.

reason: String

Description of the corruption.

InvalidCoreId

SegmentNotFound

Segment file not found.

Fields

core_id: usize

Core ID.

path: PathBuf

Expected path.

CheckpointNotFound

Checkpoint not found.

actual: u64

Actual epoch.

IncrementalCheckpoint(IncrementalCheckpointError)

Incremental checkpoint error.

Trait Implementations

impl Debug for PerCoreWalError

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

Formats the value using the given formatter.

impl Display for PerCoreWalError

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

Formats the value using the given formatter.

impl Error for PerCoreWalError

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<Error> for PerCoreWalError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<IncrementalCheckpointError> for PerCoreWalError

fn from(source: IncrementalCheckpointError) -> Self

Converts to this type from the input type.
