Trait NodeAggregatorTrait 

pub trait NodeAggregatorTrait<T: Clone + Send + Sync>: Send + Sync {
    // Required method
    fn aggregate_up(
        &self,
        start_node: &NodeId,
        state: Arc<State>,
    ) -> impl Future<Output = ForgeResult<HashMap<NodeId, T>>> + Send;
}

节点聚合器 Trait

定义树形结构的自下而上聚合计算接口

Required Methods

fn aggregate_up( &self, start_node: &NodeId, state: Arc<State>, ) -> impl Future<Output = ForgeResult<HashMap<NodeId, T>>> + Send

执行自下而上的聚合计算

参数

• start_node: 起始节点 ID（通常是叶子节点）
• state: 状态引用

返回值

所有节点的聚合结果 HashMap

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
