Enum TaskError 

pub enum TaskError<R, Route> {
    ResultAfterCompletion {
        result: R,
        reply_to: Route,
    },
    ResultAfterCancellation {
        result: R,
        reply_to: Route,
    },
    CancellationAfterCompletion {
        reply_to: Route,
    },
    CancellationAfterCancellation {
        reply_to: Route,
    },
}

Rejected terminal transition when a test or nonconforming interpreter invokes a task after its stopping action.

Variants

ResultAfterCompletion

A second result followed successful completion; ownership is returned.

Fields

result: R

reply_to: Route

ResultAfterCancellation

A result followed cancellation; ownership is returned.

Fields

result: R

reply_to: Route

CancellationAfterCompletion

Cancellation followed successful completion.

Fields

reply_to: Route

CancellationAfterCancellation

Cancellation was repeated.

Fields

reply_to: Route

Trait Implementations

impl<R: Clone, Route: Clone> Clone for TaskError<R, Route>

fn clone(&self) -> TaskError<R, Route>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R: Debug, Route: Debug> Debug for TaskError<R, Route>

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

Formats the value using the given formatter.

impl<R, Route> Display for TaskError<R, Route>

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

Formats the value using the given formatter.

impl<R, Route> Error for TaskError<R, Route>

where Self: Debug + Display,

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<R: PartialEq, Route: PartialEq> PartialEq for TaskError<R, Route>

fn eq(&self, other: &TaskError<R, Route>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
