A Rust equivalent of Unix command “which”. Locate installed executable in cross platforms.
To find which rustc executable binary is using.
use which::which; let result = which("rustc").unwrap(); assert_eq!(result, PathBuf::from("/usr/bin/rustc"));
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()));
The documentation is available online.
