Errors that can occur during incremental checkpointing.

Variants

Io(Error)

I/O error during checkpoint operations.

Serialization(String)

Serialization error.

Deserialization(String)

Deserialization error.

Wal(String)

WAL error.

NotFound(String)

Checkpoint not found.

Corruption(String)

Checkpoint corruption detected.

Recovery(String)

Recovery failed.

BufferOverflow

Buffer overflow (backpressure signal).

Fields

epoch: u64

The epoch at which overflow occurred.

InvalidConfig(String)

Invalid configuration.

AlreadyExists(u64)

Checkpoint already exists.

EpochMismatch

Epoch mismatch during recovery.

Fields

expected: u64

Expected epoch.

found: u64

Found epoch.

CrcMismatch

CRC checksum mismatch.

Fields

offset: u64

Offset where mismatch occurred.

expected: u32

Expected CRC.

computed: u32

Computed CRC.

Implementations

impl IncrementalCheckpointError

pub fn is_transient(&self) -> bool

Returns true if this error indicates a transient failure that may succeed on retry.

pub fn is_corruption(&self) -> bool

Returns true if this error indicates data corruption.

Trait Implementations

impl Debug for IncrementalCheckpointError

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

Formats the value using the given formatter.

impl Display for IncrementalCheckpointError

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

Formats the value using the given formatter.

impl Error for IncrementalCheckpointError

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 IncrementalCheckpointError

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.
