ActorRegistry

Struct ActorRegistry 

Source
pub struct ActorRegistry { /* private fields */ }
Expand description

Thread-safe registry for looking up actors by name.

Actors are registered at spawn time and can be looked up by name from any task. The registry stores type-erased refs; callers must know the actor type to downcast.

Lifecycle: Actors are auto-registered on spawn but NOT auto-unregistered on stop. Call unregister explicitly when actors terminate, or accept that stopped actors remain in the registry (their refs will report is_alive() == false).

Implementations§

Source§

impl ActorRegistry

Source

pub fn new() -> Self

Create a new empty actor registry.

Source

pub fn register<R: Clone + Send + Sync + 'static>( &self, name: &str, actor_ref: R, )

Register an actor ref under a name. Overwrites if name exists. The ref must be Clone so it can be retrieved via lookup.

Source

pub fn lookup<R: Clone + 'static>(&self, name: &str) -> Option<R>

Look up an actor by name, returning a clone of its ref. Returns None if not found or if the type doesn’t match.

Source

pub fn unregister(&self, name: &str) -> bool

Remove an actor from the registry.

Source

pub fn contains(&self, name: &str) -> bool

Check if a name is registered.

Source

pub fn len(&self) -> usize

Number of registered actors.

Source

pub fn is_empty(&self) -> bool

Whether the registry is empty.

Source

pub fn names(&self) -> Vec<String>

List all registered names.
