Trait TransitionAction 

pub trait TransitionAction: Send + Sync {
    // Required method
    fn run_sync(&self, ctx: &mut TransitionContext) -> Result<(), ActionError>;

    // Provided methods
    fn is_sync(&self) -> bool { ... }
    fn run_async<'a>(
        &'a self,
        ctx: TransitionContext,
    ) -> Pin<Box<dyn Future<Output = Result<TransitionContext, ActionError>> + Send + 'a>> { ... }
}

The action executed when a transition fires.

Actions can be sync or async. Sync actions execute inline during the firing phase for maximum performance. Async actions are dispatched to the runtime.

Required Methods

fn run_sync(&self, ctx: &mut TransitionContext) -> Result<(), ActionError>

Execute the action synchronously. Called when is_sync() returns true.

Provided Methods

fn is_sync(&self) -> bool

Returns true if this action can execute synchronously.

fn run_async<'a>( &'a self, ctx: TransitionContext, ) -> Pin<Box<dyn Future<Output = Result<TransitionContext, ActionError>> + Send + 'a>>

Execute the action asynchronously. Default implementation calls run_sync.
