Enum ActionError 

pub enum ActionError {
    Aborted,
    Disconnected,
    Transcript(Error),
    Backend(BackendError),
    Failed(String),
}

Errors that may surface from an Action handler.

Variants

Aborted

Operator requested abort. Propagated from Reporter::check_abort or Reporter::prompt.

Disconnected

Frontend channel disconnected. The executor unwinds to a failure.

Transcript(Error)

Transcript sink failed to persist a fact.

Backend(BackendError)

Underlying backend returned an error.

Failed(String)

Catch-all for handler-specific failures.

Trait Implementations

impl Debug for ActionError

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

Formats the value using the given formatter.

impl Display for ActionError

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

Formats the value using the given formatter.

impl Error for ActionError

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<BackendError> for ActionError

fn from(source: BackendError) -> Self

Converts to this type from the input type.

impl From<ReporterError> for ActionError

fn from(value: ReporterError) -> Self
