Trait Implementations

impl Clone for TaskNode

fn clone(&self) -> TaskNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl FlowNode for TaskNode

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 State, ) -> Pin<Box<dyn Future<Output = Result<NodeOutput, 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 metadata_hint(&self) -> NodeMetadata

节点元数据提示 — 静态声明节点的执行特征。
