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"));
   

2. 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()));
