Errors that can occur during queue operations.

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.

Driver(String)

The underlying database or connection failed.

Serialization(String)

Serialization/deserialization of job payloads failed.

HandlerNotFound(String)

A job handler was not found for the given job name.

JobFailed(String)

The job execution itself failed.

RuntimeUnavailable

The worker was started outside an active Tokio runtime.

InvalidConfiguration(String)

A worker option would make safe processing impossible.

StateTransition

Persisting a job state transition failed.

Fields

job_id: String

Job whose state could not be persisted.

operation: &'static str

Attempted transition operation.

message: String

Driver failure description.

JobTimedOut

A handler exceeded the configured execution deadline.

Fields

job_id: String

Timed-out job identifier.

timeout_ms: u64

Configured timeout in milliseconds.

JobPanicked

A handler panicked and was isolated by the worker.

Fields

job_id: String

Panicking job identifier.

WorkerTask(String)

An internal worker task terminated unexpectedly.

Unsupported(String)

A custom queue backend does not implement an optional lifecycle action.

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.
