Trait Implementations

impl<F> ExecutableItem for FnItem<F>

where F: FnMut(&mut Context<'_>) -> ExecuteResult + Send + 'static,

fn execute(&mut self, ctx: &mut Context<'_>) -> ExecuteResult

Called by the executor when any declared trigger fires.

fn declare_triggers( &mut self, d: &mut TriggerDeclarer<'_>, ) -> Result<(), ExecutorError>

Called once when the item is added to an executor. The implementor registers its trigger handles via the TriggerDeclarer.

fn task_id(&self) -> Option<&str>

Optional human-readable id used for monitor/observer correlation. None means “use the auto-assigned id”.

Optional application id; Some(_) enables Observer per-app callbacks.
