Type Alias DrainCheck 

pub type DrainCheck = Box<dyn Fn() -> Pin<Box<dyn Future<Output = bool> + Send>> + Send + Sync>;

A predicate that returns true once the named component has reached a clean stopped state.

The closure may be async (return a future). The probe polls it on a configurable interval until the predicate returns true or the deadline elapses.
