Struct PlacementRouter 

pub struct PlacementRouter { /* private fields */ }

Single orchestrating entry point for all capability execution in Traverse.

Wires together placement evaluation → executor selection → execution → trace recording → event publishing.

Implementations

impl PlacementRouter

pub fn new( evaluator: PlacementConstraintEvaluator, executor_registry: CapabilityExecutorRegistry, trace_store: Arc<Mutex<TraceStore>>, event_broker: Arc<dyn EventBroker>, ) -> Self

Construct a new PlacementRouter from injected dependencies.

pub fn execute( &self, request: RouterRequest, ) -> Result<RouterResponse, RouterError>

Execute a capability end-to-end.

Steps:

1. Evaluate placement constraints — returns RouterError::PlacementFailed with no trace on failure.
2. Select executor by artifact_type.
3. Run the executor.
4. Write public + private trace entries to the store.
5. If service_type == Subscribable, publish emitted events.

Errors

Returns RouterError when any step cannot complete.

pub fn execute_with_executor( &self, request: RouterRequest, executor: &dyn CapabilityExecutor, ) -> Result<RouterResponse, RouterError>

Execute a capability with an explicitly provided executor.

Used by the live Runtime::execute path to bridge a host LocalExecutor without requiring a 'static registry entry.

Errors

Returns RouterError when any step cannot complete.
