路径长度映射#
- class PathLengthMapping#
基础：
object用于返回目标节点路径长度的自定义类
该类是整数节点索引到浮点数路径长度的只读映射，形式如下：
{0: 24.5, 1: 2.1}
此类是一个容器类，用于存放返回目标节点和路径映射结果的函数。它实现了 Python 映射协议，因此您可以将其视为只读的映射/字典。如果想将其用作迭代器，可以通过将其包装在
iter()中来实现，它会按顺序生成结果。例如:
import rustworkx as rx graph = rx.generators.directed_path_graph(5) edges = rx.dijkstra_shortest_path_lengths(0) # Target node access third_element = edges[2] # Use as iterator edges_iter = iter(edges) first_target = next(edges_iter) first_path = edges[first_target] second_target = next(edges_iter) second_path = edges[second_target]
