Enum backoff::Error

pub enum Error<E> {
    Permanent(E),
    Transient(E),
}

Error is the error value in an operation's result.

Based on the two possible values, the operation may be retried.

Variants

Permanent(E)

Permanent means that it's impossible to execute the operation successfully. This error is immediately returned from retry().

Transient(E)

Transient means that the error is temporary, the operation should be retried according to the backoff policy.

Trait Implementations

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

By default all errors are transient. Permanent errors can be constructed explicitly. This implementation is for making the question mark operator (?) and the try! macro to work.

fn from(err: E) -> Error<E>

Performs the conversion.

impl<E> Display for Error<E> where
    E: Display, 

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

Formats the value using the given formatter.

impl<E> Debug for Error<E> where
    E: Debug, 

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

Formats the value using the given formatter.

impl<E> Error for Error<E> where
    E: Error, 

fn description(&self) -> &str

This method is soft-deprecated.

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

The lower-level cause of this error, if any.

default fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

default fn type_id(&self) -> TypeId where
    Self: 'static, 

Gets the TypeId of self
