<h3 id="redox"><a class="header" href="#redox">redox</a></h3>
|
||
<p><a href="https://github.com/redox-os/redox">redox</a> 是一个 <code>Unix</code> 风格的微内核操作系统，使用 <code>Rust</code> 实现。<code>redox</code> 的目标是安全、快速、免费、可用，它在内核设计上借鉴了很多优秀的内核，例如：<code>SeL4</code>, <code>MINIX</code>, <code>Plan 9</code>和<code>BSD</code>。</p>
|
||
<p>但 <code>redox</code> 不仅仅是一个内核，它还是一个功能齐全的操作系统，提供了操作系统该有的功能，例如：内存分配器、文件系统、显示管理、核心工具等等。你可以大概认为它是一个 <code>GNU</code> 或 <code>BSD</code> 生态，但是是通过一门现代化、内存安全的语言实现的。</p>
|
||
<blockquote>
|
||
<p>不过据我仔细观察，redox目前的开发进度不是很活跃，不知道发生了什么，未来若有新的发现会在这里进行更新 - Sunface</p>

<h3 id="tock"><a class="header" href="#tock">tock</a></h3>
|
||
<p><a href="https://github.com/tock/tock">tock</a> 是一个嵌入式操作系统，设计用于在低内存和低功耗的微控制器上运行多个并发的、相互不信任的应用程序，例如它可在 <code>Cortex-M</code> 和 <code>RISC-V</code> 平台上运行。</p>
|
||
<p><code>Tock</code> 使用两个核心机制保护操作系统中不同组件的安全运行：</p>
|
||
<ul>
|
||
<li>内核和设备驱动全部使用Rust编写，提供了很好安全性的同时，还将内核和设备进行了隔离</li>
|
||
<li>使用了内存保护单元技术，让应用之间、应用和内核之间实现了安全隔离</li>
|
||
</ul>
|
||
<p>具体可通过这本书了解: <a href="https://book.tockos.org/introduction.html">The Tock Book</a>.</p>

|
||
<h3 id="theseus"><a class="header" href="#theseus">Theseus</a></h3>
|
||
<p><a href="https://github.com/theseus-os/Theseus">Theseus</a> 是从零开始构建的操作系统，完全使用Rust进行开发。它使用了新的操作系统结构、更好的状态管理，以及利用语言内设计原则将操作系统的职责(如资源管理)转移到编译器中。</p>
|
||
<p>该OS目前尚处于早期阶段，但是看上去作者很有信心未来可以落地，如果想要了解，可以通过官方提供的<a href="https://theseus-os.github.io/Theseus/book/index.html">在线书籍</a>进行学习。</p>

<h3 id="rcore-os"><a class="header" href="#rcore-os">rcore-os</a></h3>

<p><a href="https://github.com/rcore-os">rcore-os</a> 是由清华大学开发的操作系统，用 Rus t实现, 与 <code>linux</code> 相兼容，主要目的目前还是用于教学，因为还有相关的配套教程，非常值得学习。目前支持的功能不完全列表如下：<code>linux</code> 兼容的 <code>syscall</code> 接口、网络协议栈、简单的文件系统、信号系统、异步IO、内核模块化。</p>
