Failure while opening or operating the durable embedded storage engine.

Variants

DataDirectory(DataDirectoryError)

The data directory could not be initialized or exclusively locked.

Log(LogError)

The authoritative log rejected or failed an operation.

Index

The rebuildable materialized index failed before a new log commit.

Fields

source: Box<MaterializedIndexError>

Rebuildable-index failure.

Mutation(MutationError)

A mutation violates the stable binary codec.

CommittedButNotIndexed

The log commit is durable but its index update failed.

Fields

receipt: CommitReceipt

Receipt proving that the log commit succeeded.

source: Box<MaterializedIndexError>

Rebuildable-index failure.

StaleIndex

Reads and further writes are blocked after an index update failure.

Snapshot

Snapshot creation or verification failed.

Fields

source: Box<SnapshotError>

Underlying snapshot failure.

ManifestGenerationExhausted

The immutable manifest generation space is exhausted.

PreparedSegmentNotEmpty

A prepared compaction segment unexpectedly contains complete frames.

Fields

path: PathBuf

Unexpected nonempty segment path.

InvalidScanLimit

A KV scan page size is zero or exceeds the hard storage bound.

Fields

requested: usize

Requested page size.

maximum: usize

Hard maximum page size.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
