Struct GraphBuilder 

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

Graph 构建器。

Implementations

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

pub fn new(name: impl Into<String>) -> Self

创建 GraphBuilder。

pub fn canonical_hash(&mut self, hash: u64) -> &mut Self

P0-2: 设置 canonical hash — 由 DSL 层（如 AgentBuilder）调用。

pub fn start(&mut self, node: impl Into<String>) -> &mut Self

pub fn end(&mut self, node: impl Into<String>) -> &mut Self

pub fn node( &mut self, name: impl Into<String>, kind: NodeKind<S, M>, ) -> &mut Self

pub fn subgraph<Inner, IM, L>( &mut self, name: impl Into<String>, spec: SubgraphSpec<S, Inner, IM, L>, ) -> &mut Self

where S: 'static, Inner: 'static + WorkflowState, IM: 'static + MergeStrategy<Inner>, L: 'static + StateLens<S, Inner>,

便捷方法 — 添加 Subgraph 节点。

pub fn edge( &mut self, from: impl Into<String>, to: impl Into<String>, ) -> PendingEdge<'_, S, M>

pub fn edge_if( &mut self, from: impl Into<String>, to: impl Into<String>, condition: impl Fn(&S) -> bool + Send + Sync + 'static, ) -> PendingEdge<'_, S, M>

pub fn edge_fallback( &mut self, from: impl Into<String>, to: impl Into<String>, ) -> PendingEdge<'_, S, M>

pub fn build(self) -> Result<Graph<S, M>, BuildErrors>

pub fn name(&self) -> &str

pub fn compile(self) -> Result<Graph<S, M>, BuildErrors>

构建并编译 — 在 build() 之后运行 Compiler Pass（如 InlinePass）。
