Type Alias ScheduleCallback 

pub type ScheduleCallback = Arc<dyn Fn() -> BoxFuture<'static, ()> + Send + Sync>;

The callback fired by a ScheduleDriver when a schedule entry triggers.

Mirrors the TS ScheduleEntry.callback: () => void | Promise<void>. The cron manager passes a closure that runs one job execution; the driver awaits it (and, for the default driver, reschedules the next cron fire afterwards).
