Struct Graph 

pub struct Graph<S: WorkflowState = State, M: MergeStrategy<S> = StateMerge> { /* private fields */ }

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

Implementations

impl<S: WorkflowState, M: MergeStrategy<S>> Graph<S, M>

pub fn name(&self) -> &str

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

pub fn start_node(&self) -> &str

pub fn end_node(&self) -> &str

pub fn hash_u64(&self) -> u64

计算图结构指纹 hash（u64 原始值）。

用于 Checkpoint 的 graph compatibility 校验。

pub fn hash(&self) -> String

计算图结构指纹 hash（hex 字符串）。

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

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

pub fn node_map(&self) -> &IndexMap<String, NodeKind<S, M>>

获取节点映射表引用。

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

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

验证图结构。

pub fn analyze(&self) -> GraphDiagnostics

完整图诊断分析。

pub fn analyze_cycles(&self) -> CycleAnalysis

@deprecated 使用 analyze() 替代。

pub async fn run_inline( &self, exec_ctx: &mut ExecutionEngine<S>, max_steps: usize, ) -> Result<(), GraphError>

内联执行 — 不产生 RuntimeEvent，不 Checkpoint。

接收 ExecutionEngine（拥有者），内部循环构建 [NodeContext]（能力视图） 供节点使用。执行完毕后通过 take_* 消费 Mutation 和控制信号。

数据流：

ExecutionEngine
  → build_node_context()  → NodeContext<'_, S>
  → node.execute(ctx)     → 节点 record() Mutations
  → drop(ctx)             → 释放借用
  → take_mutations()      → 消费 Mutation 缓冲
  → state.apply_batch()   → apply 到 State
  → take_control()        → 获取路由信号

Trait Implementations

impl<S: Clone + WorkflowState, M: Clone + MergeStrategy<S>> Clone for Graph<S, M>

fn clone(&self) -> Graph<S, M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
