Struct SupervisorHooks 

pub struct SupervisorHooks {
    pub exit_action: Option<Box<dyn FnMut(&ExitInfo) -> ExitAction + Send>>,
    pub start_gate: Option<Box<dyn FnMut(&StartGateInfo) -> StartGate + Send>>,
}

Optional decisions the supervisor asks its host (rightkit#936). Every hook runs on the supervisor thread; keep each short.

Fields

exit_action: Option<Box<dyn FnMut(&ExitInfo) -> ExitAction + Send>>

Called when a child exits by itself.

start_gate: Option<Box<dyn FnMut(&StartGateInfo) -> StartGate + Send>>

Called before every launch, the first included (a start precondition: wait for a handover).
