Enum StrategyError 

#[non_exhaustive]
pub enum StrategyError {
    InvalidTransition {
        current_state: String,
        attempted_action: String,
        valid_actions: Vec<String>,
    },
    GuardRejected(String),
    NoInitialState,
    Execution(String),
}

Execution strategy error.

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.

InvalidTransition

Invalid state transition.

Fields

current_state: String

Current state.

attempted_action: String

Attempted action.

valid_actions: Vec<String>

Valid actions from current state.

GuardRejected(String)

Guard condition rejected transition.

NoInitialState

No initial state defined.

Execution(String)

Execution failed.

Trait Implementations

impl Clone for StrategyError

fn clone(&self) -> StrategyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StrategyError

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

Formats the value using the given formatter.

impl Display for StrategyError

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

Formats the value using the given formatter.

impl Error for StrategyError

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.
