Struct ChildSpec 

pub struct ChildSpec<R: Reactor> {
    pub name: String,
    pub restart: RestartPolicy,
    pub shutdown: ShutdownPolicy,
    pub namespace: NamespacePolicy,
    pub mailbox_capacity: usize,
    pub factory: Arc<dyn Fn() -> Box<dyn Actor<R>> + Send + Sync>,
    pub stable_addr_refresher: Option<Arc<dyn AddrRefresher>>,
}

Specification provided at spawn time that governs a child actor’s lifecycle.

factory is called by the supervisor whenever it needs to (re)create the child actor — at initial spawn and after each restart. It must be Send + Sync so the supervisor task can share the spec across threads.

Fields

name: String

restart: RestartPolicy

shutdown: ShutdownPolicy

namespace: NamespacePolicy

mailbox_capacity: usize

factory: Arc<dyn Fn() -> Box<dyn Actor<R>> + Send + Sync>

Factory function that produces a fresh Box<dyn Actor<R>> on each (re)spawn. The closure must be cheap to call repeatedly.

stable_addr_refresher: Option<Arc<dyn AddrRefresher>>

Optional refresher notified by the supervisor after each (re)spawn. Set via ChildSpec::with_stable_addr.

Implementations

impl<R: Reactor> ChildSpec<R>

pub fn new( name: impl Into<String>, restart: RestartPolicy, shutdown: ShutdownPolicy, namespace: NamespacePolicy, factory: impl Fn() -> Box<dyn Actor<R>> + Send + Sync + 'static, ) -> Self

pub fn with_mailbox_capacity(self, capacity: usize) -> Self

Builder-style method to override the default mailbox capacity.

pub fn with_stable_addr(self, refresher: Arc<dyn AddrRefresher>) -> Self

Attach an AddrRefresher so the supervisor updates a [StableAddr] after each spawn of this child.
