Implementations

impl StorageError

pub fn not_found(id: impl Into<String>) -> Self

Creates a NotFound error.

pub fn invalid_path(path: impl Into<PathBuf>) -> Self

Creates an InvalidPath error.

pub fn directory_creation(path: impl Into<PathBuf>, source: Error) -> Self

Creates a DirectoryCreation error.

pub fn checksum_mismatch( session_id: impl Into<String>, expected: impl Into<String>, actual: impl Into<String>, ) -> Self

Creates a ChecksumMismatch error.

pub fn is_recoverable(&self) -> bool

Returns true if this is a recoverable error.

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.

impl From<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<SnapshotError> for StorageError

fn from(source: SnapshotError) -> Self

Converts to this type from the input type.
