Trait ProducerSignal 

pub trait ProducerSignal:

    + 'static {
    // Required methods
    fn variant_id(&self) -> EffectVariantId;
    fn field(&self, id: &FieldId) -> Option<FieldValue<'_>>;
}

Marker trait for the seam-signal source sum consumed by CompositionSignalDispatcher.

Signal-kind composition routes use the same producer-side EffectVariantId namespace as input routes, but their target is a consumer SignalVariantId. This trait mirrors ProducerEffect so signal dispatch has the same typed projection discipline without requiring callers to smuggle signal payloads through the input dispatcher.

Required Methods

fn variant_id(&self) -> EffectVariantId

Typed producer-side variant id for this signal source value.

fn field(&self, id: &FieldId) -> Option<FieldValue<'_>>

Borrow a producer field by FieldId.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
