Enum BackendError

#[non_exhaustive]
pub enum BackendError {
    TempFile(PersistError),
    Io(Error),
    Internal(String),
    Other(Error),
}

An error returned by a Backend implementor

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TempFile(PersistError)

An error occured from the tempfile

Io(Error)

An I/O Error occured

Internal(String)

An internal error occured

Other(Error)

A dynamic error occured

Most likely the custom Backend implementation has thrown an error, consult its documentation for more information

Important: This can only be used if the other_errors feature is enabled

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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.
