Struct ConditionNode 

pub struct ConditionNode {
    pub name: String,
    pub branches: Vec<(String, BranchCondition)>,
}

条件分支节点。

按声明顺序求值分支条件，返回第一个匹配分支的 NextStep::Goto(target)。 无匹配时返回 NextStep::GoToNext，由 Graph 层的 edge_fallback 处理兜底路由。

Fields

name: String

branches: Vec<(String, BranchCondition)>
