Graph

Struct Graph 

Source
pub struct Graph { /* private fields */ }
Expand description

图(Graph)— 允许有环,循环保护由 GraphExecutor::max_steps 运行时熔断提供。

Implementations§

Source§

impl Graph

Source

pub fn name(&self) -> &str

Source

pub fn node_names(&self) -> Vec<&str>

Source

pub fn start_node(&self) -> &str

Source

pub fn end_node(&self) -> &str

Source

pub fn hash(&self) -> String

计算图结构指纹 hash。

用于 Checkpoint 恢复时校验图结构是否变更。 基于节点名和边定义生成简化的 hash 字符串。

Source

pub fn edges_from(&self, from: &str) -> Vec<&Edge>

Source

pub fn find_edge(&self, from: &str, to: &str) -> Option<&Edge>

Source

pub fn find_fallback_edge(&self, from: &str) -> Option<String>

查找指定节点的 fallback 边目标。

用于 Fallback 控制流:节点主动声明降级后,Executor 查找 fallback 边路由。

Source

pub fn validate(&self) -> Result<(), TerminalError>

验证图结构(节点、边引用有效性)。

注意:不检测环 — 有环图是合法的,循环保护由 GraphExecutor::max_steps 提供。

Source

pub fn analyze(&self) -> GraphDiagnostics

完整图诊断分析。

检查以下维度并返回 GraphDiagnostics

  1. 环检测 — 图中存在循环路径(Warning)
  2. Fallback 参与循环 — fallback 边在环内(Warning)
  3. 不可达路径 — 从 start 无法到达的节点(Info)
  4. End 节点出边 — end 节点定义了出边(Info)

build() 的关系:build() 只检查结构正确性;analyze() 检查风险性。

Source

pub fn analyze_cycles(&self) -> CycleAnalysis

分析图中所有环,生成诊断信息。

@deprecated 使用 analyze() 替代。
