Struct KernelChildren 

pub struct KernelChildren {
    pub blas: ActorRef<BlasMsg>,
    pub cudnn: Option<ActorRef<CudnnMsg>>,
    pub fft: Option<ActorRef<FftMsg>>,
    pub rng: Option<ActorRef<RngMsg>>,
    pub solver: Option<ActorRef<SolverMsg>>,
    pub nvrtc: Option<ActorRef<NvrtcMsg>>,
    /* private fields */
}

Set of kernel-actor refs spawned by a ContextActor. Each is Some only when both the cargo feature is compiled in and the DeviceConfig::enabled_libraries flag is set.

Phase 0.8 extension. In addition to the typed fields below (which keep existing call sites compiling), KernelChildren carries an open extras map keyed by TypeId. Future actor crates (atomr-accel-cutlass, -tensorrt, -flashattn, -telemetry, -cub) stash their ActorRef here so the device supervisor can hand them out via KernelChildren::extra without the core having to know their concrete message type.

Fields

blas: ActorRef<BlasMsg>

cudnn: Option<ActorRef<CudnnMsg>>

fft: Option<ActorRef<FftMsg>>

rng: Option<ActorRef<RngMsg>>

solver: Option<ActorRef<SolverMsg>>

nvrtc: Option<ActorRef<NvrtcMsg>>

Implementations

impl KernelChildren

pub fn new(blas: ActorRef<BlasMsg>) -> Self

Construct a KernelChildren with the given BlasActor ref and no library children or extras. Mirrors the ..Default::default() pattern used by callers but keeps blas mandatory.

pub fn register_extra<T: Any + Send + Sync>(&self, value: T)

Register an extra child actor (or any Send + Sync handle) by type. Future actor crates (atomr-accel-cutlass, -tensorrt, -flashattn, -telemetry, -cub) stash their ActorRef here so the device supervisor can route stop/restart messages.

If a value of the same type is already registered, it is overwritten — typical use is one-shot registration during ContextActor::run_init.

pub fn extra<T: Any + Send + Sync + Clone>(&self) -> Option<T>

Look up a previously registered extra by type. Returns a clone of the stored T if and only if a value of that exact type was registered.

pub fn extras_len(&self) -> usize

Number of registered extras (for stats / observability).

Trait Implementations

impl Clone for KernelChildren

fn clone(&self) -> KernelChildren

Returns a duplicate of the value.

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

Performs copy-assignment from source.
