Enum StatusMachineError 

#[non_exhaustive]
pub enum StatusMachineError {
    Transition(StatusTransitionError),
    Ownership(OwnershipError),
}

Combined error type for the state machine.

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.

Transition(StatusTransitionError)

Ownership(OwnershipError)

Trait Implementations

impl Clone for StatusMachineError

fn clone(&self) -> StatusMachineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatusMachineError

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

Formats the value using the given formatter.

impl Display for StatusMachineError

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

impl Error for StatusMachineError

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>)
