Struct StateMachine 

pub struct StateMachine<'a, C> {
    pub memory: Arc<RwLock<Map<String, Value>>>,
    pub context: Arc<RwLock<C>>,
    /* private fields */
}

The state machine containing all states, the current state, memory, context, and handlers.

Fields

memory: Arc<RwLock<Map<String, Value>>>

The memory used by the state machine to store data.

context: Arc<RwLock<C>>

The context used by the state machine to store state.

Implementations

impl<C> StateMachine<'_, C>

pub fn new<F>( config_content: &str, initial_state: Option<String>, action_handler: F, memory: Map<String, Value>, context: C, ) -> Result<Self, String>

where F: for<'b> Fn(&'b Action, &'b mut Map<String, Value>, &'b mut C) -> Pin<Box<dyn Future<Output = ()> + Send + 'b>> + Send + Sync + 'static,

Creates a new state machine from a JSON configuration string.

pub async fn trigger(&self, event: &str) -> Result<(), String>

Triggers an event, causing a state transition if applicable and executing actions.

pub async fn get_current_state(&self) -> Result<String, String>

Returns the current state of the state machine.

Trait Implementations

impl<C> Display for StateMachine<'_, C>

Implementing the Display trait to render the state machine as a string.

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

Formats the value using the given formatter.
