本节包含链表的一些常用操作，如删除、插入和合并等。 常见错误有 遍历链表不向前递推节点，遍历链表前未保存头节点，返回链表节点指针错误。 下图是把本章中所有出现的题目归类总结了一下，便于记忆

链表是线性表的一种。线性表是最基本、最简单、也是最常用的一种数据结构。线性表中数据元素之间的关系是一对一的关系，即除了第一个和最后一个数据元素之外，其它数据元素都是首尾相接的。线性表有两种存储方式，一种是顺序存储结构，另一种是链式存储结构。我们常用的数组就是一种典型的顺序存储结构。 相反，链式存储结构就是两个相邻的元素在内存中可能不是相邻的，每一个元素都有一个指针域，指针域一般是存储着到下一个元素

对一个结构体来说，须对各个元素逐个实现 fmt::Display 可能会很麻烦。问题在于每个 write! 都要生成一个 fmt::Result。彻底地实现需要处理所有的结果。出于这方面考虑，Rust 提供了 try! 宏。 在 write! 上使用 try!类似这样： // 对 `write!` 进行尝试（try），观察是否出错。若发生错误，返回相应的错误。 // 否则（没有出错）继续执行后面的
