### Get Project, Base, and User Directories

Source: https://github.com/dirs/directories-rs/blob/main/README.md

This example demonstrates how to obtain configuration, cache, and data directories for a specific project, as well as general base and user directories. It shows how to access config_dir, executable_dir, and audio_dir. Note that some directories might not be available on all platforms.

```rust
extern crate directories;
use directories::{BaseDirs, UserDirs, ProjectDirs};

if let Some(proj_dirs) = ProjectDirs::from("com", "Foo Corp",  "Bar App") {
    proj_dirs.config_dir();
    // Lin: /home/alice/.config/barapp
    // Win: C:\Users\Alice\AppData\Roaming\Foo Corp\Bar App\config
    // Mac: /Users/Alice/Library/Application Support/com.Foo-Corp.Bar-App
}

if let Some(base_dirs) = BaseDirs::new() {
    base_dirs.executable_dir();
    // Lin: Some(/home/alice/.local/bin)
    // Win: None
    // Mac: None
}

if let Some(user_dirs) = UserDirs::new() {
    user_dirs.audio_dir();
    // Lin: /home/alice/Music
    // Win: C:\Users\Alice\Music
    // Mac: /Users/Alice/Music
}
```

### Cross-Compilation Build Targets

Source: https://github.com/dirs/directories-rs/blob/main/README.md

Build the library on various platforms for cross-compilation. Ensure necessary toolchains are installed with rustup.

```bash
cargo build --target=x86_64-unknown-linux-gnu
cargo build --target=x86_64-pc-windows-gnu
cargo build --target=x86_64-apple-darwin
cargo build --target=x86_64-unknown-redox
```

--------------------------------

### Create ProjectDirs Instance

Source: https://github.com/dirs/directories-rs/blob/main/README.md

Instantiate ProjectDirs by providing a qualifier, organization, and application name. The resulting path varies by operating system.

```rust
ProjectDirs::from("org", /*qualifier*/
                  "Baz Corp", /*organization*/
                  "Foo Bar-App" /*application*/)
```

--------------------------------

### Create ProjectDirs from Path

Source: https://github.com/dirs/directories-rs/blob/main/README.md

Create a ProjectDirs instance directly from a PathBuf. This method is discouraged as it may not adhere to operating system standards.

```rust
ProjectDirs::from_path(path: &Path)
```

--------------------------------

### ProjectDirs Path Values

Source: https://github.com/dirs/directories-rs/blob/main/README.md

Illustrates the computed path values for cache, config, and data directories across different operating systems based on the provided project details.

```text
Value on Linux | Value on Windows         | Value on macOS               
| -------------- | ------------------------ | ---------------------------- 
| "foobar-app" | "Baz Corp/Foo Bar-App" | "org.Baz-Corp.Foo-Bar-App"
```

--------------------------------

### Add directories to Cargo.toml

Source: https://github.com/dirs/directories-rs/blob/main/README.md

Add the 'directories' library as a dependency to your project by including this line in your Cargo.toml file.

```toml
directories = "6.0"
```
