Error type for WAL operations.

Variants

Io(Error)

Serialization(String)

Serialization error when writing entries.

Deserialization(String)

Deserialization error when reading entries.

Corrupted

Corrupted WAL entry detected (incomplete record).

Fields

position: u64

Position where corruption was detected.

reason: String

Reason for corruption.

ChecksumMismatch

CRC32 checksum mismatch.

Fields

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

position: u64

Position where torn write was detected.

reason: String

Description of the torn write.

Trait Implementations

impl Debug for WalError

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

Formats the value using the given formatter.

impl Display for WalError

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

Formats the value using the given formatter.

impl Error for WalError

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 WalError

fn from(source: Error) -> Self

Converts to this type from the input type.
