Struct ConditionNode 

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

条件分支节点。

Fields

name: String

branches: Vec<(String, BranchCondition)>

otherwise_target: Option<String>

兜底目标 — 当所有 branch 条件均不匹配时，跳转到此节点。 未设置时，无匹配则返回 TerminalError。

Implementations

Trait Implementations

impl GraphNode for ConditionNode

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, state: &'life1 mut State, ) -> Pin<Box<dyn Future<Output = Result<NextStep, GraphError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

执行节点逻辑（阻塞模式）。

fn execute_stream<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, state: &'life1 mut State, _sink: &'life2 Sender<GraphEvent>, span_id: SpanId, ) -> Pin<Box<dyn Future<Output = Result<StreamNodeResult, GraphError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

执行节点逻辑（流式模式），将内部事件转发到 channel。
