Struct Edge 

pub struct Edge<S: WorkflowState = State> {
    pub from: String,
    pub to: String,
    pub condition: Option<EdgeCondition<S>>,
    pub analysis: Option<EdgeAnalysis>,
    pub fallback: bool,
}

边（Edge）— 三类边模型。

Fields

from: String

to: String

condition: Option<EdgeCondition<S>>

路由条件。Some = 条件边；None = 普通边或 fallback 边。

analysis: Option<EdgeAnalysis>

分析用约束（不参与 runtime 决策）

fallback: bool

是否为 fallback 边（最后兜底）

Implementations

impl<S: WorkflowState> Edge<S>

pub fn is_conditional(&self) -> bool

判断是否为条件边。

pub fn is_normal(&self) -> bool

判断是否为普通边（无条件非 fallback）。

Trait Implementations

impl<S: Clone + WorkflowState> Clone for Edge<S>

fn clone(&self) -> Edge<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: WorkflowState> Debug for Edge<S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
