Struct SubprocessCallbackInvoker 

pub struct SubprocessCallbackInvoker { /* private fields */ }

Subprocess-backed CallbackInvoker.

Spawns a fresh child per invocation. The protocol is intentionally minimal: stdin receives a single JSON-serialized DispatchEnvelope (carrying the crate::CallbackRequest and any opaque PayloadEnvelope bodies); stdout returns a single JSON-serialized CallbackResponse. The child must exit zero on success. Anything outside that contract surfaces as a typed SubprocessInvokerError.

Payload bodies

Payload bodies flow through the subprocess channel inside the DispatchEnvelope (issue #22). Bodies are transported verbatim: Lifeloop never parses body or dereferences body_ref. Clients receive the same envelopes a caller passed to CallbackInvoker::invoke.

pub fn config(&self) -> &SubprocessInvokerConfig

Trait Implementations

impl CallbackInvoker for SubprocessCallbackInvoker

type Error = SubprocessInvokerError

Error produced by the callback transport. Kept generic so a renderer-backed impl, an in-process impl, and a future network impl can each carry their own diagnostic shape.

fn invoke( &self, plan: &RoutingPlan, payloads: &[PayloadEnvelope], ) -> Result<CallbackResponse, Self::Error>

Invoke the client callback for a routed event.

impl Clone for SubprocessCallbackInvoker

fn clone(&self) -> SubprocessCallbackInvoker

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SubprocessCallbackInvoker

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
