Errors returned by the storage layer: failed preconditions, corrupt or unsupported durable state, resource exhaustion, and invalid read requests.

Variants

Unhealthy

A poisoned storage lock fenced the store; reopen is required.

Precondition

A transaction precondition was violated; path is the offending key.

Fields

path: String

Key whose precondition failed.

Builder(String)

The deterministic expander failed while building a commit.

CorruptLog

A durable record could not be decoded or verified.

UnsupportedCommandVersion(u32)

A log record carries a command version this build does not support.

OutcomePayload

The stored outcome payload is missing or cannot be deserialized.

Durability(String)

The physical backend failed while applying or reading durable state.

SnapshotExpired

The requested snapshot predates the oldest retained commit.

Fields

requested: u64

Snapshot commit index that was requested.

oldest: u64

Oldest commit index still readable.

FutureSnapshot

The requested snapshot is newer than the visible commit index.

Fields

requested: u64

Snapshot commit index that was requested.

visible: u64

Commit index currently visible.

ResourceExhausted(String)

A managed byte budget refused the request.

InvalidConfiguration(String)

The supplied storage configuration is not valid.

Cancelled

A pinned read was cancelled by its caller.

InvalidRead(String)

Scan bounds or batch limits are invalid.

ReadersActive

Physical compaction was requested while protected read views are open.

ConflictHistoryUnavailable

No conflict summary is retained for a commit that must be probed.

Fields

commit_index: u64

Commit index whose conflict summary is missing.

Trait Implementations

impl Clone for StorageError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
