# 标准的Package目录结构
|
||
|
|
一个典型的 `Package` 目录结构如下：
|
||
|
|
```shell
|
||
|
|
.
|
||
|
|
├── Cargo.lock
|
||
|
|
├── Cargo.toml
|
||
|
|
├── src/
|
||
|
|
│ ├── lib.rs
|
||
|
|
│ ├── main.rs
|
||
|
|
│ └── bin/
|
||
|
|
│ ├── named-executable.rs
|
||
|
|
│ ├── another-executable.rs
|
||
|
|
│ └── multi-file-executable/
|
||
|
|
│ ├── main.rs
|
||
|
|
│ └── some_module.rs
|
||
|
|
├── benches/
|
||
|
|
│ ├── large-input.rs
|
||
|
|
│ └── multi-file-bench/
|
||
|
|
│ ├── main.rs
|
||
|
|
│ └── bench_module.rs
|
||
|
|
├── examples/
|
||
|
|
│ ├── simple.rs
|
||
|
|
│ └── multi-file-example/
|
||
|
|
│ ├── main.rs
|
||
|
|
│ └── ex_module.rs
|
||
|
|
└── tests/
|
||
|
|
├── some-integration-tests.rs
|
||
|
|
└── multi-file-test/
|
||
|
|
├── main.rs
|
||
|
|
└── test_module.rs
|
||
|
|
```
|
||
|
|
|
||
|
|
这也是 `Cargo` 推荐的目录结构，解释如下：
|
||
|
|
|
||
|
|
- `Cargo.toml` 和 `Cargo.lock` 保存在 `package` 根目录下
|
||
|
|
- 源代码放在 `src` 目录下
|
||
|
|
- 默认的 `lib` 包根是 `src/lib.rs`
|
||
|
|
- 默认的二进制包根是 `src/main.rs`
|
||
|
|
- 其它二进制包根放在 `src/bin/` 目录下
|
||
|
|
- 基准测试 benchmark 放在 `benches` 目录下
|
||
|
|
- 示例代码放在 `examples` 目录下
|
||
|
|
- 集成测试代码放在 `tests` 目录下
|
||
|
|
|
||
|
|
|

关于 Rust 中的包和模块，[之前的章节](https://course.rs/basic/crate-module/intro.html)有更详细的解释。

这里的一些目录配置还能通过配置文件来修改，详情参见本章的后续章节[修改默认的文件目录](https://course.rs/cargo/reference/manifest/cargo-target.html)
