Trait Implementations

impl GraphNode for TaskNode

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）。

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。
