Implementations

impl StorageError

pub fn driver( capability: StorageCapability, operation: impl Into<Cow<'static, str>>, source: impl StdError + Send + Sync + 'static, ) -> Self

Construct a Driver error wrapping a backend-specific error source.

pub fn capability(&self) -> Option<StorageCapability>

Return the storage capability surface that produced this error, if any.

pub fn is_retryable(&self) -> bool

Whether this error is transient and the operation may succeed on retry.

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.
