Trait Implementations

impl CapabilityError for StoreError

fn category(&self) -> ErrorCategory

Returns the category of this error for generic handling.

fn is_transient(&self) -> bool

Returns true if the underlying condition may clear without changing the request.

fn is_retryable(&self) -> bool

Returns true if retrying the operation makes sense given typical idempotency.

fn retry_after(&self) -> Option<Duration>

Returns the suggested delay before retrying, if known.

impl Clone for StoreError

fn clone(&self) -> StoreError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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>)
