|
|
|
|
|
|
<p><strong>结构体</strong>（<em>struct</em>），或者 <em>structure</em>，是一个自定义数据类型，允许你包装和命名多个相关的值，从而形成一个有意义的组合。如果你熟悉一门面向对象语言，你会发现一个 struct 就像对象的数据属性。在本章中，我们会比较元组和结构体的异同，在你已有知识的基础上进一步探讨，并演示在何种情况下结构体是组合数据的更好方式。</p>
|
|
|
|
|
|
<p>我们还将演示如何定义和实例化结构体，并讨论如何定义关联函数，特别是被称为 <em>方法</em> 的那种关联函数，以指定与结构体类型相关的行为。你可以在程序中基于结构体和枚举（<em>enum</em>）（在第六章介绍）创建新类型，以充分利用 Rust 的编译时类型检查。</p>
