Enum WorkerError 

#[non_exhaustive]
pub enum WorkerError {
    BackendError(BoxDynError),
    StateError(WorkerStateError),
    PanicError(String),
    IoError(Error),
}

Possible errors that can occur when running a worker.

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.

BackendError(BoxDynError)

An error occurred while polling.

StateError(WorkerStateError)

An error occurred while trying to change the state of the worker.

PanicError(String)

A worker panicked and the panic was caught.

IoError(Error)

An error occurred while handling io

Trait Implementations

impl Debug for WorkerError

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

Formats the value using the given formatter.

impl Display for WorkerError

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

Formats the value using the given formatter.

impl Error for WorkerError

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 WorkerError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<WorkerStateError> for WorkerError

fn from(source: WorkerStateError) -> Self

Converts to this type from the input type.
