Struct CollectiveActor 

pub struct CollectiveActor { /* private fields */ }

Implementations

impl CollectiveActor

pub fn props_for_rank( comm: Comm, state: Arc<DeviceState>, completion: Arc<dyn CompletionStrategy>, ) -> Props<Self>

Build a Props<CollectiveActor> capturing a single-rank Comm. Each call constructs a single-shot factory (the comm cannot be cloned). The returned Props panics on second instantiation — supervisor restart loops therefore become fatal for NCCL world actors. NcclWorldActor handles this by orchestrating world rebuilds explicitly.

pub fn mock_props() -> Props<Self>

Trait Implementations

impl Actor for CollectiveActor

type Msg = CollectiveMsg

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, msg: CollectiveMsg, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Process a single message.

fn pre_start<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called once before the first message.

fn post_stop<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called after the actor has been stopped.

fn pre_restart<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, _err: &'life2 str, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Called when the actor is about to be restarted by the supervisor.

fn post_restart<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, _err: &'life2 str, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Called after a restart.

fn on_terminated<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _ctx: &'life1 mut Context<Self>, _path: &'life2 ActorPath, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

Called when a watched actor terminates. The path argument is the path of the actor that just stopped. Default is a no-op. Implementations may translate this into a user-visible message (the Python binding does this for Terminated events).

fn supervisor_strategy(&self) -> SupervisorStrategy

The supervisor strategy this actor applies to its own children.
