向DeepSeek的提问

帮我设计以下两个python class
Span
属性：
hash值（在init函数中通过时间初始化）
创建时间：时间（在init函数中通过时间初始化）
结束时间：时间（可选，默认为空）
子Span：数组对象类型为Span
parent：父Span
状态：打开，关闭
内容：str对象，若对象为非str类型string化。

函数
结束：如果当前Span的所有子Span都结束了，则可以结束（要求这个函数线程安全）
展示：按照当前Span和子Span的创建和时间顺序发挥Span

Span_Mgr
函数
查询最近所有的父Span，按照时间顺序返回
创建一个新的Span（输入内容），返回Span对象

你可以使用ExpiringDictStorage作为数据持久化的实现方式，以下为ExpiringDictStorage的定义
