Source

pub struct ActorContext<A: ActorLike> {
    pub rx: <A::Channel as ActorChannel>::Receiver,

Expand description

Runtime context for an active actor instance.

This structure contains all the necessary components for an actor’s execution, including message reception, cancellation handling, and task spawning capabilities.

Fields§

§rx: <A::Channel as ActorChannel>::Receiver

Message receiver for incoming actor messages

§token: CancelToken<A::Cancel>

Cancellation token for graceful shutdown

§futures: JoinSet<()>

Task set for managing spawned futures

§span: Span

Tracing span for observability

§link: WeakLink<A>

Weak reference to the actor’s link

Implementations§

Source §

impl<A: Actor> ActorContext<A>

Source

pub fn spawn(&mut self, future: impl Future<Output = ()> + Send + 'static)

Spawn a background task within the actor’s context.

The spawned task will be automatically cancelled when the actor shuts down.

Auto Trait Implementations§

§

impl<A> Freeze for ActorContext<A>
where <<A as ActorLike>::Channel as ActorChannel>::Receiver: Freeze,

§

impl<A> Unpin for ActorContext<A>
where <<A as ActorLike>::Channel as ActorChannel>::Receiver: Unpin,

§

impl<A> !UnwindSafe for ActorContext<A>

Blanket Implementations§

Source §

impl<T> Any for T
where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

impl<T> BorrowMut<T> for T
where T: ?Sized,

Source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

Source §

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
