Enum Error 

pub enum Error {
    Serde(Error),
    Backend(Box<dyn Error + Send + Sync + 'static>),
    UnknownQueue(String),
    NoHandler(String),
    DuplicateHandler(String),
    ShutDown,
    ConsumerStopped(String),
}

Infrastructure-level errors (serialization, transport, configuration).

Variants

Serde(Error)

A job payload or envelope could not be (de)serialized.

Backend(Box<dyn Error + Send + Sync + 'static>)

The transport failed.

UnknownQueue(String)

A queue name that is not part of the queue set was used.

NoHandler(String)

No handler is registered for a job type.

DuplicateHandler(String)

Two handlers claimed the same Job::NAME.

ShutDown

The worker or backend is shut down.

ConsumerStopped(String)

A consumer stream ended on its own, which means the backend went away.

Implementations

impl Error

pub fn backend<E: Error + Send + Sync + 'static>(e: E) -> Self

Wrap a transport error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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) -> Self

Converts to this type from the input type.
