Typed errors of the storage-mode marker (spec section 5.3). Mirrors the subsystem-error idiom of crate::locks::LockError; [From<StorageModeError> for MongrelError] maps onto the closest existing engine variants.

Variants

ClusterReplicaRequiresClusterRuntime

A normal open path touched a cluster-replica database.

Fields

cluster_id: ClusterId

Owning cluster.

node_id: NodeId

Owning node.

database_id: DatabaseId

Replicated database.

IdentityMismatch(String)

The cluster runtime offered an identity that disagrees with the marker (fail closed: opening the wrong replica would corrupt two clusters).

Corrupt

The marker failed validation (fails closed).

Fields

reason: String

Why the marker failed validation.

UnsupportedVersion

The marker was written by a newer format than this build supports.

Fields

found: u16

Version found on disk.

supported: u16

Version this build writes.

Conflict(String)

A mode change was requested (spec section 5.2 forbids in-place conversion).

Io(Error)

Underlying I/O failure.

Trait Implementations

impl Debug for StorageModeError

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

Formats the value using the given formatter.

impl Display for StorageModeError

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

Formats the value using the given formatter.

impl Error for StorageModeError

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 StorageModeError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<StorageModeError> for MongrelError

fn from(error: StorageModeError) -> Self

Converts to this type from the input type.
