Enum QueueError 

#[non_exhaustive]
pub enum QueueError {
    Serialize(Error),
    Backend(Box<dyn Error + Send + Sync>),
}

A failure enqueuing a job through a JobProducer (or the push convenience over it).

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.

Serialize(Error)

The job could not be serialized to its JSON wire form.

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

The backend rejected or failed the enqueue. The concrete backend failure is the source, kept opaque so the producer contract stays backend-agnostic.

Implementations

impl QueueError

pub fn backend<E>(source: E) -> Self

where E: Error + Send + Sync + 'static,

Wrap a backend-specific enqueue failure as QueueError::Backend. A backend calls this to surface its concrete error (an apalis/Redis error, an SQS SDK error, …) without this crate naming the type — e.g. storage.push(job).await.map_err(QueueError::backend)?.

Trait Implementations

impl Debug for QueueError

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

Formats the value using the given formatter.

impl Display for QueueError

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

Formats the value using the given formatter.

impl Error for QueueError

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 QueueError

fn from(source: Error) -> Self

Converts to this type from the input type.
