Implementations

impl MimeError

pub fn detector_backend( backend: impl Into<String>, reason: impl Into<String>, ) -> Self

Builds a detector backend error.

Parameters

• backend: Detector backend identifier.
• reason: Why the backend failed.

Returns

A MimeError::DetectorBackend value.

Trait Implementations

impl Debug for MimeError

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

Formats the value using the given formatter.

impl Display for MimeError

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

Formats the value using the given formatter.

impl Error for MimeError

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>)
