Enum DriveFailure 

#[non_exhaustive]
pub enum DriveFailure<E, SE> {
    Step(E),
    Source(SE),
    Protocol(ProtocolViolation),
    Input(InputError),
}

Failure of a drive over any ByteStepper.

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.

Step(E)

The stage failed (for an image decoder: the decoder, its sink or the pulse).

Source(SE)

The source failed.

Protocol(ProtocolViolation)

The stage broke the protocol.

Input(InputError)

Input admission or allocation failed before a source read.

Implementations

impl<E> DriveFailure<E, Infallible>

pub fn widen<SE>(self) -> DriveFailure<E, SE>

Widen a source-free failure to any source error.

Trait Implementations

impl<E: Debug, SE: Debug> Debug for DriveFailure<E, SE>

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

Formats the value using the given formatter.

impl<E: Display, SE: Display> Display for DriveFailure<E, SE>

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

Formats the value using the given formatter.

impl<E: Error + 'static, SE: Error + 'static> Error for DriveFailure<E, SE>

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>)
