Enum StateMachineError 

pub enum StateMachineError {
    InvalidState(String),
    InvalidTransition(String),
    TransitionNotAllowed {
        transition: String,
        from: String,
    },
    RoleNotAuthorized {
        role: String,
        transition: String,
    },
    GuardFailed(String),
    FinalStateReached(String),
}

Shared error type for all state machines.

Generated modules re-export this via: pub use backbone_core::state_machine::StateMachineError;

Trait Implementations

impl Clone for StateMachineError

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 StateMachineError

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

Formats the value using the given formatter.

impl Display for StateMachineError

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

Formats the value using the given formatter.

impl Error for StateMachineError

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.
