SubGraph

Struct SubGraph 

Source
pub struct SubGraph {
    pub nodes: Vec<Arc<dyn GraphNode>>,
    pub edges: Vec<Edge>,
}
Expand description

子图(LoopNode 的执行单元)。

注意: SubGraph 内的节点不支持按名跳转(NextStep::Goto), 因为节点没有名字。需要条件回跳请使用外层 Graph 的 edge_if

Fields§

§nodes: Vec<Arc<dyn GraphNode>>§edges: Vec<Edge>

Implementations§

Source§

impl SubGraph

Source

pub fn new() -> Self

Source

pub async fn execute(&self, state: &mut State) -> Result<(), GraphError>

线性执行子图内所有节点,尊重 NextStep 语义。

  • GoToNext — 继续遍历下一个节点
  • End — 提前退出子图(后续节点不再执行)
  • Goto(target) — 报错(SubGraph 不支持按名跳转)
