GraphEdge

Struct GraphEdge 

Source
pub struct GraphEdge {
    pub weight: Option<i32>,
    pub edge_type: Option<String>,
}
Expand description

图边数据,对应原C++的GraphEdge类

在petgraph架构中,边数据存储与边关联的附加信息。与原C++实现不同, 边的连接关系(from/to)完全由petgraph的图结构管理,这里只存储边的属性。

§设计考虑

  • 权重类型:使用整数而非浮点数,避免浮点数比较的精度问题
  • 可选字段:所有字段都是可选的,支持轻量级边创建
  • 类型标识:支持不同类型的边(如路径边、约束边等)

§使用场景

use rlwfc::GraphEdge;

// 简单边
let simple_edge = GraphEdge::new();

// 带权重的边
let weighted_edge = GraphEdge::with_weight(10);

// 带类型的边
let typed_edge = GraphEdge::with_type("path".to_string());

Fields§

§weight: Option<i32>

可选的边权重(使用整数避免浮点数比较问题)

权重可用于:

  • 路径查找算法的成本计算
  • 连接强度的表示
  • 优先级排序
§edge_type: Option<String>

可选的边类型标识

类型标识可用于:

  • 区分不同种类的连接
  • 过滤特定类型的边
  • 调试和可视化
