Trait ExecutorState

Source

pub trait ExecutorState<S: WorkflowState>: ExecutionView<S> {
    // Required methods
    fn build_node_context(&mut self) -> NodeContext<'_, S>;
    fn build_leaf_context(&mut self) -> LeafContext<'_, S>;
    fn clone_state(&self) -> S;
    fn replace_state(&mut self, state: S);
    fn apply_batch(&mut self, mutations: impl IntoIterator<Item = S::Mutation>);
    fn take_control(&mut self) -> (NextAction, Option<ExecutionSignal>);
    fn take_metadata(&mut self) -> NodeMetadata;
    fn take_flow_events(&mut self) -> Vec<FlowEvent>;
    fn emit_flow_event(&mut self, event: FlowEvent);
}

完整能力 — Composite 节点 + LeafAdapter 使用。

§注意

此 trait 不是 dyn compatible（build_node_context 返回带生命周期的 NodeContext， apply_batch 使用泛型）。仅用于静态分发（T: ExecutorState<S>），不用于 dyn ExecutorState<S>。
