Expand description

节点执行 trait。

Required Methods§

Source

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 mut State, ) -> Pin<Box<dyn Future<Output = Result<NextStep, GraphError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

执行节点逻辑（阻塞模式）。

Provided Methods§

Source

fn execute_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, state: &'life1 mut State, _sink: &'life2 Sender<GraphEvent>, span_id: SpanId, ) -> Pin<Box<dyn Future<Output = Result<StreamNodeResult, GraphError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

执行节点逻辑（流式模式），将内部事件转发到 channel。

  • sink — 事件输出 channel
  • span_id — 执行实例 ID（由 executor 生成）

默认实现直接调用 execute，返回 StreamNodeResult::Done。 AgentNode 覆写此方法以转发 AgentEvent。 BarrierNode 覆写此方法以返回 StreamNodeResult::BarrierPaused。

Dyn Compatibility§

This trait is dyn compatible.

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