Struct CatalogCompositionSignalDispatcher 

pub struct CatalogCompositionSignalDispatcher<S: ProducerSignal> { /* private fields */ }

Default catalog-backed signal dispatcher.

This is the signal-kind mirror of CatalogCompositionDispatcher: it consumes the same RouteTable but resolves through the signal index and delivers to SignalConsumerSurface.

Implementations

impl<S: ProducerSignal> CatalogCompositionSignalDispatcher<S>

pub fn new(composition: CompositionId, table: RouteTable) -> Self

Build a new signal dispatcher for composition.

pub fn with_consumer(self, surface: Arc<dyn SignalConsumerSurface>) -> Self

Register a signal consumer surface for a target instance.
