Module error 

Error taxonomy and the supervisor decider for context-poisoning recovery (§5.3, §5.11 of the architecture document).

Rakka’s supervisor (atomr_core::supervision::Decider) inspects a panic message string rather than a typed error value. To trigger the doc’s OneForOne::default().on::<ContextPoisoned>(Restart) behaviour, an actor that detects context poisoning panics with a message containing the string "ContextPoisoned". The decider exposed here parses these markers back into supervisor directives.

Structs

DeviceSupervisor

Typed SupervisorOf<ContextActor> adapter for DeviceActor.

Enums

Constants

CONTEXT_POISONED_TAG

Marker prefix used in panic messages to signal a poisoned-context error. Matched by decider.

OUT_OF_MEMORY_TAG

Marker prefix for OOM errors that the supervisor should Resume past.

UNRECOVERABLE_TAG

Marker prefix for fatal errors that should stop the device entirely.

Functions

decider

The supervisor decider used by DeviceActor to route ContextActor failures (§5.11).

device_supervisor_strategy

Build the SupervisorStrategy DeviceActor applies to its ContextActor child (§5.11). Three retries inside a one-minute window; past that, the circuit opens and the device stops.
