Struct SystemHandle 

pub struct SystemHandle { /* private fields */ }

Public, opaque handle to the running super::ActorSystem that an actor can use to reach a small, curated subset of the system surface — currently just Self::scheduler. The handle holds a Weak reference so it does not keep the system alive; callers must check Self::is_alive (or receive None from Self::scheduler) before relying on it.

This type is the canonical way for binding layers (e.g. pycore) to register cancellable timers from inside Actor::handle without spawning detached tokio::spawn tasks. The internal ActorSystemInner type is crate-private, so this thin wrapper is the only stable public path.

Implementations

impl SystemHandle

pub fn is_alive(&self) -> bool

True if the underlying super::ActorSystem has not been dropped.

pub fn scheduler(&self) -> Option<Arc<dyn Scheduler>>

Borrow the system’s Scheduler. Returns None if the system has been dropped.

Trait Implementations

impl Clone for SystemHandle

fn clone(&self) -> SystemHandle

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
