@FunctionalInterface
public interface ContextualEffectAction
extends Serializable

Represents a context-aware action to be executed as a signal effect. The action receives an EffectContext that provides information about why the effect is running, such as whether it is the initial execution or whether the change originated from a background context.

Signal effects automatically track dependencies on all signals that are read during the action execution. When any of those signals change, the action is re-run with updated dependencies.
