< p > 很多人都在学 Rust ing， ， ， < / p >
< p > Rust 是一门全新的语言，它会带给你前所未有的体验，提升你的通用编程水平，甚至于赋予你全新的编程思想。在此时此刻，大家可能还半信半疑，但是当学完它再回头看时，你肯定也会认同这些貌似浮夸的赞美。< / p >
< h2 id = "避免试一试的心态" > < a class = "header" href = "#避免试一试的心态" > 避免试一试的心态< / a > < / h2 >
< p > 在学习 Go、Python 等编程语言时，你可能会一边工作、一边轻松愉快的学习它们，但是 Rust 不行。原因如文章开头所说，在学习 Rust 的同时你会收获很多语言之外的知识，因此 Rust 在入门阶段比很多编程语言要更难，但是一旦入门，你将收获一个全新的自己，成为一个更加优秀的程序员。< / p >
< p > 在学习过程中，一开始可能会轻松愉快，但是在开始接触 Rust 核心概念时（所有权、借用、生命周期、智能指针等），难度会陡然提升，此时就需要认真对待起来，否则会为后面埋下难以填补的坑：结果最后你可能只有两个选择 —— 重新学 or 放弃。< / p >
< p > 因此，在学习过程中，给大家三点建议：< / p >
< ul >
< li > 要提前做好会遇到困难的准备，因为如上所说，学习 Rust 不仅仅是在学习一门编程语言< / li >
< li > 不要抱着试一试的心态去试一试， ， ， < / li >
< li > 深入学习一本好书或教程< / li >
< / ul >
< p > 总之， ： ） < / p >
< h2 id = "深入学习一本好书" > < a class = "header" href = "#深入学习一本好书" > 深入学习一本好书< / a > < / h2 >
< p > Rust 跟其它语言不同，你无法看了一遍语法，然后就能上手写代码，对，我说的就是对比 Go 语言，后者的简单易用是有目共睹的。< / p >
< p > 这些年，我遇到过太多在网上看了一遍菜鸟教程(或其它简易教程)就上手写 demo 甚至项目的同学，无一例外，都各种碰壁、趟坑，最后要么放弃，要么回炉重造，之前的时间和精力基本等同浪费。< / p >
< p > 因此，大家一定要舍得投入时间，沉下心去读一本好书，这本书会带你深入浅出地学习使用 Rust 所需的各种知识，还会带你提前趟坑，这些坑往往是需要大量的时间才能领悟的。< / p >
< p > 在以前我可能会推荐看 Rust Book + async book + nomicon 这几本英文书的组合，但是现在有了一本更适合中国用户的书籍，那就是…你们猜，内容好坏大家一读即知，光就文字而言，那绝对是行云流水般的阅读体验，可以极大提升学习效率，也不再因为反复读也读不懂一句话而烦闷不堪。< / p >

< p > 我的天，在 Rust 中< strong > 千万别这么干< / strong > ，你是在扼杀自己之前的努力！因为不像其它语言，链表在 Rust 中简直是地狱一般的难度，我见过太多英雄好汉难过链表关，最终黯然退幕。我不希望正在阅读此文的你也成为其中一个 :（ < / p >
< p > 这些自引用类型（一种数据结构，它内部的某个字段又引用了其自身），它们堪称恶魔：不仅仅在蹂躏着新手，还在折磨着老手。有意思的是，它们的难恰恰是 Rust 的优点导致的：无 GC 也无手动内存管理还要做到内存安全。< / p >
< p > 这些优点并不是凭空产生，而是来源于 Rust 那一套强大、优美的机制，这些机制一旦你学到，就会被它巧妙的构思和设计征服，进而被 Rust 深深吸引！但是一切选择都有利弊，这种机制的弊端就在于实现链表这类数据结构时，会变得非常非常复杂。< / p >
< p > 你需要糅合各种知识，才能解决这个问题，但是这显然不是一个新手应该独自去面对的。总之，不会链表对于 Rust 的学习和写项目，真的没有任何影响，直接使用大神已经写好的数据结构就可以。< / p >
< p > 如果想要练手，我们可以换个方向开始，例如书中的入门和进阶实战项目都是非常好的选择。当然如果你就是喜欢征服困难，那没问题，就从链表开始。但是无论选择哪个，本书都将给你莫大的帮助，包括如何实现一个链表！< / p >

< p > 在一些编程语言中，你可能习惯了编译器给出的错误只看前面（或后面）几行，毕竟大部分是没啥大用的堆栈信息，在此过程中， < code > how stupid the 编译器 is< / code > 的感想时不时会迸发出来。< / p >
< p > 但是 Rust 不是，它为我们提供了一个强大无比的编译器，而且会提示我们该如何修改代码以解决错误，简直就是一名优秀的老师！< / p >
< p > 因此在使用 Rust 过程中，如果你不知该如何解决错误，不妨仔细阅读下编译器或者 IDE 给出的错误提示，绝大多数时候，都可以通过这些提示顺利的解决问题。< / p >
< p > 同时也不要忽略编译器给出的警告信息(warnings)，因为里面包含了 < code > cargo clippy< / code > 给出的 < code > lint< / code > 提示，这些提示不仅仅包含代码风格，甚至包含了一些隐藏很深的错误！至于这些错误为何不是 < code > error< / code > 形式出现，随着学习的深入，你将逐渐理解 Rust 的各种设计选择，包括这个问题。< / p >

< p > 大多数其它编程语言适用的最佳实践在 Rust 中也可以很好的使用，但是 Rust 并不是一门专门的面向对象或者函数式语言，因此在使用自己喜欢的编程风格时，也要考虑遵循 Rust 应有的实践。< / p >
< p > 例如纯面向对象或纯函数式编程，在 Rust 中就并不是一个很好的选择。如果你有过 Go 语言的编程经验，相信能更加理解我这里想表达的含义。< / p >
< p > 不过大家也不用担心，在书中我们会以专题的形式专门讲解 Rust 的最佳实践，看完后自然就明白了。< / p >

< p > 对于新手而言，最应该避免的就是从< strong > 链表开始练手< / strong > ，最应该做的就是认真仔细地学习一本优秀而全面的书。< / p >
< p > 总之，认真学 Rust， ， < strong > 相信自己，你的前方会是星辰大海！< / strong > < / p >
