Source§

impl NodeExecutor for StartNode

Source§

fn execute<'life0, 'async_trait>( &'life0 self, ctx: NodeContext, ) -> Pin<Box<dyn Future<Output = Result<Value, WorkflowError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

执行开始节点逻辑

  1. 解析节点配置中的输入定义
  2. 验证工作流上下文中的 payload 数据是否符合定义
