}

Errors that can occur during task operations.

Variants

Cancelled

Task was cancelled before completion

Panicked

Task panicked during execution

Timeout

Task exceeded its execution time limit

ResourceExhausted

Task failed due to resource exhaustion

InvalidOperation

Task failed due to an invalid operation

ExecutionFailed(TaskErrorKind)

Generic task execution error

ExecutionTimeout

Task execution timed out waiting for completion

ResultNotFound

Task result was not found in storage

SpawnFailed

Task failed to spawn

InvalidState

Task is not in a valid state for the operation

AlreadyCompleted

Task has already completed

Trait Implementations

impl Clone for TaskError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskError

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

Formats the value using the given formatter.

impl Display for TaskError

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

Formats the value using the given formatter.

impl Eq for TaskError

impl Error for TaskError

Available on crate feature std only.

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 PartialEq for TaskError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
