Implementations

impl Error

pub fn backend_failure(&self) -> Option<BackendFailure>

pub fn backend( operation: &'static str, kind: BackendFailure, source: impl Error + Send + Sync + 'static, ) -> Error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl<E> From<Error> for Error<E>

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Refusal> for Error

fn from(refusal: Refusal) -> Error

Converts to this type from the input type.
