-## 自引用
-本文分为上下两篇，试图彻底解决困扰大家已久的循环引用和自引用问题，因此难度较高，但是非常值得深入阅读，它会让你对Rust的理解上升到一个新的境界。
+## 结构体自引用
+结构体自引用在Rust中是一个众所周知的难题，而且众说纷纭，也没有一篇文章能把相关的话题讲透，那本文就王婆卖瓜，来试试看能不能讲透这一块儿内容，让读者大大们舒心。

+> 这章内容足足花了半个月的时间来准备！ - 来自作者的诉苦
 
 ## 使用Pin来解决自引用
 Pin在后续章节会深入讲解，目前你只需要知道它可以固定住一个值，防止该值的所有权被转移。通过Pin也可以实现自引用的数据结构:

 ## 总结
-本文深入讲解了何为引用循环以及如何使用Weak来解决，同时还结合`Rc`、`RefCell`、`Weak`等实现了两个有实战价值的例子，让大家对智能指针的使用更加融会贯通。

-至此，智能指针一章即将结束(严格来说还有一个Mutex放在多线程一章讲解)，而Rust语言本身的学习之旅也即将结束，后面我们将深入多线程、项目工程、应用实践、性能分析等特色专题，来一睹Rust在这些领域的风采。
