}

Failure while creating, verifying, or restoring a portable backup.

Variants

DestinationExists(PathBuf)

The requested destination already exists and is never replaced.

DestinationInsideDataDirectory(PathBuf)

A backup destination inside the live directory would couple lifecycles.

RestoreInsideBackup(PathBuf)

A restore destination inside its source backup is unsafe.

InvalidLayout

The backup directory does not contain exactly the canonical two files.

Fields

path: PathBuf

Backup path being validated.

reason: &'static str

Stable validation reason.

InvalidManifest

The bounded JSON manifest is malformed or disagrees with its snapshot.

Fields

path: PathBuf

Manifest path being validated.

reason: &'static str

Stable validation reason.

ManifestJson

Backup JSON could not be decoded.

Fields

path: PathBuf

Manifest path being decoded.

source: Error

JSON decoding failure.

Snapshot(SnapshotError)

Snapshot creation or validation failed.

Storage(StorageError)

Opening or validating restored storage failed before activation.

Io

A filesystem operation failed.

Fields

action: &'static str

Operation being performed.

path: PathBuf

Path involved in the operation.

source: Error

Operating-system failure.

Trait Implementations

impl Debug for BackupError

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

Formats the value using the given formatter.

impl Display for BackupError

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

Formats the value using the given formatter.

impl Error for BackupError

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<SnapshotError> for BackupError

fn from(source: SnapshotError) -> Self

Converts to this type from the input type.

impl From<StorageError> for BackupError

fn from(source: StorageError) -> Self

Converts to this type from the input type.
