# which

A Rust equivalent of Unix command "which". Locate installed executable in cross platforms.

## Support platforms

* Linux
* Windows
* macOS

## Examples

1) To find which rustc executable binary is using.

    ``` rust
    use which::which;

    let result = which("rustc").unwrap();
    assert_eq!(result, PathBuf::from("/usr/bin/rustc"));
    ```

2. After enabling the `regex` feature, find all cargo subcommand executables on the path:

    ``` rust
    use which::which_re;

    which_re(Regex::new("^cargo-.*").unwrap()).unwrap()
        .for_each(|pth| println!("{}", pth.to_string_lossy()));
    ```
