</ul>
<p>下面,我们将对其中一些部分进行详细讲解。</p>
<h2 id="package"><a class="header" href="#package">[package]</a></h2>
<p><code>Cargo.toml</code> 中第一个部分就是 <code>package</code>,用于设置项目的相关信息:</p>
<pre><code class="language-toml">[package]
name = &quot;hello_world&quot; # the name of the package
version = &quot;0.1.0&quot; # the current version, obeying semver
authors = [&quot;Alice &lt;a@example.com&gt;&quot;, &quot;Bob &lt;b@example.com&gt;&quot;]
</code></pre>
<p>其中,只有 <code>name</code><code>version</code> 字段是<strong>必须填写的</strong>。当发布到注册服务时,可能会有额外的字段要求,具体参见<a href="publishing-on-crates.io.html">发布到 crates.io</a></p>
<h4 id="name"><a class="header" href="#name">name</a></h4>
<p>项目名用于引用一个项目( <code>package</code> ),它有几个用途:</p>
<ul>
<li>其它项目引用我们的 <code>package</code> 时,会使用该 <code>name</code></li>
<li>编译出的可执行文件(bin target)的默认名称</li>
</ul>
<p><code>name</code> 只能使用 <a href="https://doc.rust-lang.org/stable/std/primitive.char.html#method.is_alphanumeric"><code>alphanumeric</code></a> 字符、 <code>-</code><code>_</code>,并且不能为空。</p>
<p>事实上,<code>name</code> 的限制不止如此,例如:</p>
<ul>
<li><strong>当使用 <code>cargo new</code><code>cargo init</code> 创建时</strong><code>name</code> 还会被施加额外的限制,例如不能使用 Rust 关键字名称作为 <code>name</code></li>
<li><strong>如果要发布到 <code>crates.io</code> ,那还有更多的限制</strong>: <code>name</code> 使用 <code>ASCII</code> 码,不能使用已经被使用的名称,例如 <code>uuid</code> 已经在 <code>crates.io</code> 上被使用,因此我们只能使用类如 <code>uuid_v1</code> 的名称,才能将项目发布到 <code>crates.io</code></li>
</ul>
<h4 id="version"><a class="header" href="#version">version</a></h4>
<p>Cargo 使用了<a href="https://semver.org">语义化版本控制</a>的概念,例如字符串 <code>&quot;0.1.12&quot;</code> 是一个 <code>semver</code> 格式的版本号,符合 <code>&quot;x.y.z&quot;</code> 的形式,其中 <code>x</code> 被称为主版本<code>major</code>, <code>y</code> 被称为小版本 <code>minor</code> ,而 <code>z</code> 被称为补丁 <code>patch</code>,可以看出从左到右,版本的影响范围逐步降低,补丁的更新是无关痛痒的,并不会造成 API 的兼容性被破坏。</p>
<p>使用该规则,你还需要遵循一些基本规则:</p>
<ul>
<li>使用标准的 <code>x.y.z</code> 形式的版本号,例如 <code>1.0.0</code> 而不是 <code>1.0</code></li>
<li>在版本到达 <code>1.0.0</code> 之前,怎么都行,但是如果有破坏性变更( breaking changes ),需要增加 <code>minor</code> 版本号。例如,为结构体新增字段或为枚举新增成员就是一种破坏性变更</li>
<li><code>1.0.0</code> 之后,如果发生破坏性变更,需要增加 <code>major</code> 版本号</li>
<li><code>1.0.0</code> 之后不要去破坏构建流程</li>
<li><code>1.0.0</code> 之后,不要在 <code>patch</code> 更新中添加新的 <code>api</code> ( <code>pub</code> 声明),如果要添加新的 <code>pub</code> 结构体、特征、类型、函数、方法等对象时,增加 <code>minor</code> 版本号</li>
</ul>
<p>如果大家想知道 Rust 如何使用版本号来解析依赖,可以查看<a href="https://doc.rust-lang.org/stable/cargo/reference/resolver.html">这里</a>。同时 <a href="https://doc.rust-lang.org/stable/cargo/reference/semver.html">SemVer 兼容性</a> 提供了更为详尽的破坏性变更列表。</p>
<h4 id="authors"><a class="header" href="#authors">authors</a></h4>
<pre><code class="language-toml">[package]
authors = [&quot;Sunfei &lt;contact@im.dev&gt;&quot;]
</code></pre>
<p>该字段仅用于项目的元信息描述和 <code>build.rs</code> 用到的 <code>CARGO_PKG_AUTHORS</code> 环境变量,它并不会显示在 <code>crates.io</code> 界面上。</p>
<blockquote>
<p>警告:清单中的 <code>[package]</code> 部分一旦发布到 <code>crates.io</code> 就无法进行更改,因此对于已发布的包来说,<code>authors</code> 字段是无法修改的</p>
</blockquote>
<h4 id="edition"><a class="header" href="#edition">edition</a></h4>
<p>可选字段,用于指定项目所使用的 <a href="https://course.rs/appendix/rust-version.html">Rust Edition</a></p>
<p>该配置将影响项目中的所有 <code>Cargo Target</code> 和包前者包含测试用例、benchmark、可执行文件、示例等。</p>
<pre><code class="language-toml">[package]
# ...
edition = '2021'
</code></pre>
<p>大多数时候,我们都无需手动指定,因为 <code>cargo new</code> 的时候,会自动帮我们添加。若 <code>edition</code> 配置不存在,那 <code>2015 Edition</code> 会被默认使用。</p>
<h4 id="rust-version"><a class="header" href="#rust-version">rust-version</a></h4>
<p>可选字段,用于说明你的项目支持的最低 Rust 版本(编译器能顺利完成编译)。一旦你使用的 Rust 版本比这个字段设置的要低,<code>Cargo</code> 就会报错,然后告诉用户所需的最低版本。</p>
<p>该字段是在 Rust 1.56 引入的,若大家使用的 Rust 版本低于该版本,则该字段会被自动忽略时。</p>
<pre><code class="language-toml">[package]
# ...
edition = '2021'
rust-version = &quot;1.56&quot;
</code></pre>
<p>还有一点,<code>rust-version</code> 必须比第一个引入 <code>edition</code> 的 Rust 版本要新。例如 Rust Edition 2021 是在 Rust 1.56 版本引入的,若你使用了 <code>edition = '2021'</code><code>[package]</code> 配置,则指定的 <code>rust version</code> 字段必须要要大于等于 <code>1.56</code> 版本。</p>
<p>还可以使用 <code>--ignore-rust-version</code> 命令行参数来忽略 <code>rust-version</code></p>
<p>该字段将影响项目中的所有 <code>Cargo Target</code> 和包前者包含测试用例、benchmark、可执行文件、示例等。</p>
<h2 id="description"><a class="header" href="#description">description</a></h2>
<p>该字段是项目的简介,<code>crates.io</code> 会在项目首页使用该字段包含的内容,<strong>不支持 <code>Markdown</code> 格式</strong></p>
<pre><code class="language-toml">[package]
# ...
description = &quot;A short description of my package&quot;
</code></pre>
<blockquote>
<p>注意: 若发布 <code>crates.io</code> ,则该字段是必须的</p>
</blockquote>
<h2 id="documentation"><a class="header" href="#documentation">documentation</a></h2>
<p>该字段用于说明项目文档的地址,若没有设置,<code>crates.io</code> 会自动链接到 <code>docs.rs</code> 上的相应页面。</p>
<pre><code class="language-toml">[package]
# ...
documentation = &quot;https://docs.rs/bitflags&quot;
</code></pre>
<h4 id="readme"><a class="header" href="#readme">readme</a></h4>
<p><code>readme</code> 字段指向项目的 <code>README.md</code> 文件,该文件应该存在项目的根目录下(跟 <code>Cargo.toml</code> 同级),用于向用户描述项目的详细信息,支持 <code>Markdown</code> 格式。大家看到的 <code>crates.io</code> 上的项目首页就是基于该文件的内容进行渲染的。</p>
<pre><code class="language-toml">[package]
# ...
readme = &quot;README.md&quot;
</code></pre>
<p>若该字段未设置且项目根目录下存在 <code>README.md</code><code>README.txt</code><code>README</code> 文件,则该文件的名称将被默认使用。</p>
<p>你也可以通过将 <code>readme</code> 设置为 <code>false</code> 来禁止该功能,若设置为 <code>true</code> ,则默认值 <code>README.md</code> 将被使用。</p>
<h4 id="homepage"><a class="header" href="#homepage">homepage</a></h4>
<p>该字段用于设置项目主页的 URL:</p>
<pre><code class="language-toml">[package]
# ...
homepage = &quot;https://serde.rs/&quot;
</code></pre>
<h4 id="repository"><a class="header" href="#repository">repository</a></h4>
<p>设置项目的源代码仓库地址,例如 <code>GitHub</code> 链接:</p>
<pre><code class="language-toml">[package]
# ...
repository = &quot;https://github.com/rust-lang/cargo/&quot;
</code></pre>
<h4 id="license-和-license-file"><a class="header" href="#license-和-license-file">license 和 license-file</a></h4>
<p><code>license</code> 字段用于描述项目所遵循的开源协议。而 <code>license-file</code> 则用于指定包含开源协议的文件所在的路径(相对于 <code>Cargo.toml</code>)。</p>
<p>如果要发布到 <code>crates.io</code> ,则该协议必须是 <a href="https://spdx.dev/spdx-specification-21-web-version/#h.jxpfx0ykyb60">SPDX2.1 协议表达式</a>。同时 <code>license</code> 名称必须是来自于 <a href="https://github.com/spdx/license-list-data/tree/v3.11">SPDX 协议列表 3.11</a></p>
<p>SPDX 只支持使用 <code>AND</code><code>OR</code> 来组合多个开源协议:</p>
<pre><code class="language-toml">[package]
# ...
license = &quot;MIT OR Apache-2.0&quot;
</code></pre>
<p><code>OR</code> 代表用户可以任选一个协议进行遵循,而 <code>AND</code> 表示用户必须要同时遵循两个协议。还可以通过 <code>WITH</code> 来在指定协议之外添加额外的要求:</p>
<ul>
<li><code>MIT OR Apache-2.0</code></li>
<li><code>LGPL-2.1-only AND MIT AND BSD-2-Clause</code></li>
<li><code>GPL-2.0-or-later WITH Bison-exception-2.2</code></li>
</ul>
<p><strong>若项目使用了非标准的协议</strong>,你可以通过指定 <code>license-file</code> 字段来替代 <code>license</code> 的使用:</p>
<pre><code class="language-toml">[package]
# ...
license-file = &quot;LICENSE.txt&quot;
</code></pre>
<blockquote>
<p>注意crates.io 要求必须设置 <code>license</code><code>license-file</code></p>
</blockquote>
<h4 id="keywords"><a class="header" href="#keywords">keywords</a></h4>
<p>该字段使用字符串数组的方式来指定项目的关键字列表,当用户在 <code>crates.io</code> 上搜索时,这些关键字可以提供索引的功能。</p>
<pre><code class="language-toml">[package]
# ...
keywords = [&quot;gamedev&quot;, &quot;graphics&quot;]
</code></pre>
<blockquote>
<p>注意:<code>crates.io</code> 最多只支持 5 个关键字,每个关键字都必须是合法的 <code>ASCII</code> 文本,且需要使用字母作为开头,只能包含字母、数字、<code>_</code><code>-</code>,最多支持 20 个字符长度</p>
</blockquote>
<h4 id="categories"><a class="header" href="#categories">categories</a></h4>
<p><code>categories</code> 用于描述项目所属的类别:</p>
<pre><code class="language-toml">categories = [&quot;command-line-utilities&quot;, &quot;development-tools::cargo-plugins&quot;]
</code></pre>
<blockquote>
<p>注意:<code>crates.io</code> 最多只支持 5 个类别,目前不支持用户随意自定义类别,你所使用的类别需要跟 <a href="https://crates.io/category_slugs">https://crates.io/category_slugs</a> 上的类别<strong>精准匹配</strong></p>
</blockquote>
<h4 id="workspace"><a class="header" href="#workspace">workspace</a></h4>
<p>该字段用于配置当前项目所属的工作空间。</p>
<p>若没有设置,则将沿着文件目录向上寻找,直至找到第一个 设置了 <code>[workspace]</code><code>Cargo.toml</code>。因此,当一个成员不在工作空间的子目录时,设置该字段将非常有用。</p>
<pre><code class="language-toml">[package]
# ...
workspace = &quot;path/to/workspace/root&quot;
</code></pre>
<p>需要注意的是 <code>Cargo.toml</code> 清单还有一个 <code>[workspace]</code> 部分专门用于设置工作空间,若它被设置了,则 <code>package</code> 中的 <code>workspace</code> 字段将无法被指定。这是因为一个包无法同时满足两个角色:</p>
<ul>
<li>该包是工作空间的根包(root crate),通过 <code>[workspace]</code> 指定)</li>
<li>该包是另一个工作空间的成员,通过 <code>package.workspace</code> 指定</li>
</ul>
<p>若要了解工作空间的更多信息,请参见<a href="https://course.rs/cargo/reference/workspaces.html">这里</a></p>
<h4 id="build"><a class="header" href="#build">build</a></h4>
<p><code>build</code> 用于指定位于项目根目录中的构建脚本,关于构建脚本的更多信息,可以阅读 <a href="https://course.rs/cargo/reference/build-script/intro.html">构建脚本</a> 一章。</p>
<pre><code class="language-toml">[package]
# ...
build = &quot;build.rs&quot;
</code></pre>
<p>还可以使用 <code>build = false</code> 来禁止构建脚本的自动检测。</p>
<h4 id="links"><a class="header" href="#links">links</a></h4>
<p>用于指定项目链接的本地库的名称,更多的信息请看构建脚本章节的 <a href="https://course.rs/cargo/reference/build-script/intro.html#links">links</a></p>
<pre><code class="language-toml">[package]
# ...
links = &quot;foo&quot;
</code></pre>
<h4 id="exclude-和-include"><a class="header" href="#exclude-和-include">exclude 和 include</a></h4>
<p>这两个字段可以用于显式地指定想要包含在外或在内的文件列表,往往用于发布到注册服务时。你可以使用 <code>cargo package --list</code> 来检查哪些文件被包含在项目中。</p>
<pre><code class="language-toml">[package]
# ...
exclude = [&quot;/ci&quot;, &quot;images/&quot;, &quot;.*&quot;]
</code></pre>
<pre><code class="language-toml">[package]
# ...
include = [&quot;/src&quot;, &quot;COPYRIGHT&quot;, &quot;/examples&quot;, &quot;!/examples/big_example&quot;]
</code></pre>
<p>尽管大家可能没有指定 <code>include</code><code>exclude</code>,但是任然会有些规则自动被应用,一起来看看。</p>
<p><code>include</code> 没有被指定,则以下文件将被排除在外:</p>
<ul>
<li>项目不是 git 仓库,则所有以 <code>.</code> 开头的隐藏文件会被排除</li>
<li>项目是 git 仓库,通过 <code>.gitignore</code> 配置的文件会被排除</li>
</ul>
<p>无论 <code>include</code><code>exclude</code> 是否被指定,以下文件都会被排除在外:</p>
<ul>
<li>任何包含 <code>Cargo.toml</code> 的子目录会被排除</li>
<li>根目录下的 <code>target</code> 目录会被排除</li>
</ul>
<p>以下文件会永远被 <code>include</code> ,你无需显式地指定:</p>
<ul>
<li><code>Cargo.toml</code></li>
<li>若项目包含可执行文件或示例代码,则最小化的 <code>Cargo.lock</code> 会自动被包含</li>
<li><code>license-file</code> 指定的协议文件</li>
</ul>
<blockquote>
<p>这两个字段很强大,但是对于生产实践而言,我们还是推荐通过 <code>.gitignore</code> 来控制,因为这样协作者更容易看懂。如果大家希望更深入的了解 <code>include/exclude</code>,可以参考下官方的 <code>Cargo</code> <a href="https://doc.rust-lang.org/stable/cargo/reference/manifest.html?search=#the-exclude-and-include-fields">文档</a></p>
</blockquote>
<h4 id="publish"><a class="header" href="#publish">publish</a></h4>
<p>该字段常常用于防止项目因为失误被发布到 <code>crates.io</code> 等注册服务上,例如如果希望项目在公司内部私有化,你应该设置:</p>
<pre><code class="language-toml">[package]
# ...
publish = false
</code></pre>
<p>也可以通过字符串数组的方式来指定允许发布到的注册服务名称:</p>
<pre><code class="language-toml">[package]
# ...
publish = [&quot;some-registry-name&quot;]
</code></pre>
<p><code>publish</code> 数组中包含了一个注册服务名称,则 <code>cargo publish</code> 命令会使用该注册服务,除非你通过 <code>--registry</code> 来设定额外的规则。</p>
<h4 id="metadata"><a class="header" href="#metadata">metadata</a></h4>
<p>Cargo 默认情况下会对 <code>Cargo.toml</code> 中未使用的 <code>key</code> 进行警告,以帮助大家提前发现风险。但是 <code>package.metadata</code> 并不在其中,因为它是由用户自定义的提供给外部工具的配置文件。例如:</p>
<pre><code class="language-toml">[package]
name = &quot;...&quot;
# ...
# 以下配置元数据可以在生成安卓 APK 时使用
[package.metadata.android]
package-name = &quot;my-awesome-android-app&quot;
assets = &quot;path/to/static&quot;
</code></pre>
<p>与其相似的还有 <code>[workspace.metadata]</code>,都可以作为外部工具的配置信息来使用。</p>
<h4 id="default-run"><a class="header" href="#default-run">default-run</a></h4>
<p>当大家使用 <code>cargo run</code> 来运行项目时,该命令会使用默认的二进制可执行文件作为程序启动入口。</p>
<p>我们可以通过 <code>default-run</code> 来修改默认的入口,例如现在有两个二进制文件 <code>src/bin/a.rs</code><code>src/bin/b.rs</code>,通过以下配置可以将入口设置为前者:</p>
<pre><code class="language-toml">[package]
default-run = &quot;a&quot;
</code></pre>
<h2 id="badges"><a class="header" href="#badges">[badges]</a></h2>
<p>该部分用于指定项目当前的状态,该状态会展示在 <code>crates.io</code> 的项目主页中,例如以下配置可以设置项目的维护状态:</p>
<pre><code class="language-toml">[badges]
# `maintenance` 是项目的当前维护状态,它可能会被其它注册服务所使用,但是目前还没有被 `crates.io` 使用: https://github.com/rust-lang/crates.io/issues/2437
#
# `status` 字段时必须的,以下是可用的选项:
# - `actively-developed`: 新特性正在积极添加中bug 在持续修复中
# - `passively-maintained`: 目前没有计划去支持新的特性,但是项目维护者可能会回答你提出的 issue
# - `as-is`: 该项目的功能已经完结,维护者不准备继续开发和提供支持了,但是它的功能已经达到了预期
# - `experimental`: 作者希望同大家分享,但是还不准备满足任何人的特殊要求
# - `looking-for-maintainer`: 当前维护者希望将项目转移给新的维护者
# - `deprecated`: 不再推荐使用该项目,需要说明原因以及推荐的替代项目
# - `none`: 不显示任何 badge ,因此维护者没有说明他们的状态,用户需要自己去调查发生了什么
maintenance = { status = &quot;...&quot; }
</code></pre>
<h2 id="dependencies"><a class="header" href="#dependencies">[dependencies]</a></h2>
<p><a href="https://course.rs/cargo/reference/specify-deps.html">之前章节</a>中,我们已经详细介绍过 <code>[dependencies]</code><code>[dev-dependencies]</code><code>[build-dependencies]</code>,这里就不再赘述。</p>
<h2 id="profile"><a class="header" href="#profile">[profile.*]</a></h2>
<p>该部分可以对编译器进行配置,例如 debug 和优化,在后续的<a href="https://course.rs/cargo/reference/profiles.html">编译器优化</a>章节有详细介绍。</p>
