Struct DeviceSupervisor 

pub struct DeviceSupervisor;

Typed SupervisorOf<ContextActor> adapter for DeviceActor.

atomr 0.2.0 added the [SupervisorOf] trait so a parent can decide child failures by pattern-matching a typed error rather than parsing the panic-string. The implementation here lives behind the [device_supervisor] zero-sized type so it can be used either independently (DeviceSupervisor.decide(&err)) or attached to future call sites that take a SupervisorOf<C> constraint.

We attach the impl to a marker rather than directly to DeviceActor so that the error module stays free of a circular dependency on device::DeviceActor / device::ContextActor. The decision logic is identical to the closure in decider — and indeed DeviceSupervisor::decide_str is what the closure-based code path internally calls.

Implementations

impl DeviceSupervisor

pub fn decide(err: &GpuError) -> Directive

Typed decider over &GpuError. Mirrors the panic-string match in decider.

pub fn decide_str(panic_msg: &str) -> Directive

Convenience: decide directly from the panic-string transport. Equivalent to invoking decider but available as a free function for callers who already have the panic message in hand.

Trait Implementations

impl<C> SupervisorOf<C> for DeviceSupervisor

where C: Actor,

Blanket SupervisorOf<C> impl: any atomr actor C whose failures the application classifies as GpuError can be supervised by this marker. The trait’s decide method dispatches to DeviceSupervisor::decide.

type ChildError = GpuError

The child’s error type. Implementations choose this; the recommended pattern is one error enum per supervised child type.

fn decide(&self, err: &GpuError) -> Directive

Decide what to do when the child fails with err. Defaults to Restart.
