which

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

Support platforms

  • Linux
  • Windows

Examples

  1. To find which rustc executable binary is using.

    use which::which;
    
    let result = which("rustc").unwrap();
    assert_eq!(result, PathBuf::from("/usr/bin/rustc"));
    
  1. After enabling the regex feature, find all cargo subcommand executables on the path:

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

MSRV

This crate currently has an MSRV of Rust 1.63. Increasing the MSRV is considered a breaking change and thus requires a major version bump.
