<h1 id="通过-configtoml-对-cargo-进行配置"><a class="header" href="#通过-configtoml-对-cargo-进行配置">通过 config.toml 对 Cargo 进行配置</a></h1>
<p>Cargo 相关的配置有两种,第一种是对自身进行配置,第二种是对指定的项目进行配置,关于后者请查看 <a href="https://course.rs/cargo/reference/manifest.html">Cargo.toml 清单</a>。对于普通用户而言第二种才是我们最常使用的。</p>
<p>本文讲述的是如何对 Cargo 相关的工具进行配置,该配置中的部分内容可能会覆盖掉 <code>Cargo.toml</code> 中对应的部分,例如关于 <code>profile</code> 的内容。</p>
<h2 id="层级结构"><a class="header" href="#层级结构">层级结构</a></h2>
<p>在前面我们已经见识过如何为 Cargo 进行全局配置:<code>$HOME/.cargo/config.toml</code>,事实上,还支持在一个 <code>package</code> 内对它进行配置。</p>
<p>总体原则是:<code>Cargo</code> 会顺着当前目录往上查找,直到找到目标配置文件。例如我们在目录 <code>/projects/foo/bar/baz</code> 下调用 Cargo 命令,那查找路径如下所示:</p>
<ul>
<li><code>/projects/foo/bar/baz/.cargo/config.toml</code></li>
<li><code>/projects/foo/bar/.cargo/config.toml</code></li>
<li><code>/projects/foo/.cargo/config.toml</code></li>
<li><code>/projects/.cargo/config.toml</code></li>
<li><code>/.cargo/config.toml</code></li>
<li><code>$CARGO_HOME/config.toml</code> 默认是 :
<ul>
<li>Windows: <code>%USERPROFILE%\.cargo\config.toml</code></li>
<li>Unix: <code>$HOME/.cargo/config.toml</code></li>
</ul>
</li>
</ul>
<p>有了这种机制,我们既可以在全局中设置默认的配置,又可以每个包都设定独立的配置,甚至还能做版本控制。</p>
<p>如果一个 <code>key</code> 在多个配置中出现,那这些 <code>key</code> 只会保留一个:最靠近 Cargo 执行目录的配置文件中的 key 的值将被最终使用(因此, $HOME 下的都是最低优先级)。<strong>需要注意的是,如果 <code>key</code> 的值是数组,那相应的值将被合并( join )</strong></p>
<p>对于工作空间而言,<code>Cargo</code> 的搜索策略是从 root 开始,对于内部成员中包含的 <code>.cargo.toml</code> 会自动忽略。例如一个工作空间拥有两个成员,每个成员都有配置文件: <code>/projects/foo/bar/baz/mylib/.cargo/config.toml</code><code>/projects/foo/bar/baz/mybin/.cargo/config.toml</code>,但是 <code>Cargo</code> 并不会读取它们而是从工作空间的根( <code>/projects/foo/bar/baz/</code> )开始往上查找。</p>
<blockquote>
<p>注意Cargo 还支持没有 <code>.toml</code> 后缀的 <code>.cargo/config</code> 文件。对于 <code>.toml</code> 的支持是从 Rust 1.39 版本开始,同时也是目前最推荐的方式。<strong>但若同时存在有后缀和无后缀的文件Cargo 将使用无后缀的!</strong></p>

<h2 id="环境变量"><a class="header" href="#环境变量">环境变量</a></h2>
<p>除了 <code>config.toml</code> 配置文件,我们还可以使用环境变量的方式对 Cargo 进行配置。</p>
<p>配置文件的中的 key <code>foo.bar</code> 对应的环境变量形式为 <code>CARGO_FOO_BAR</code>,其中的<code>.</code><code>-</code> 被转换成 <code>_</code>,且字母都变成大写的。例如,<code>target.x86_64-unknown-linux-gnu.runner</code> key 转换成环境变量后变成 <code>CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUNNER</code></p>
<p>就优先级而言环境变量是比配置文件更高的。除了上面的机制Cargo 还支持一些<a href="https://doc.rust-lang.org/stable/cargo/reference/environment-variables.html">预定义的环境变量</a></p>
<blockquote>
<p>官方 Cargo Book 中本文的内容还有<a href="https://doc.rust-lang.org/stable/cargo/reference/config.html#configuration-keys">很多</a>,但是剩余内容对于绝大多数用户都用不到,因此我们并没有涵盖其中。</p>
