 创建一个不链接标准库的 Rust 可执行文件，将是我们迈出的第一步。无需底层操作系统的支撑，这样才能在**裸机**（[bare metal]）上运行 Rust 代码。

 在这篇文章中，我们将基于 **x86架构**（the x86 architecture），使用 Rust 语言，编写一个最小化的 64 位内核。我们将从上一章中构建的独立式可执行程序开始，构建自己的内核；它将向显示器打印字符串，并能被打包为一个能够引导启动的**磁盘映像**（disk image）。

 **VGA 字符模式**（[VGA text mode]）是打印字符到屏幕的一种简单方式。在这篇文章中，为了包装这个模式为一个安全而简单的接口，我们将包装 unsafe 代码到独立的模块。我们还将实现对 Rust 语言**格式化宏**（[formatting macros]）的支持。

 本文主要讲述了在`no_std`环境下进行单元测试和集成测试的方法。我们将通过Rust的自定义测试框架来在我们的内核中执行一些测试函数。为了将结果反馈到QEMU上，我们需要使用QEMU的一些其他的功能以及`bootimage`工具。
