I’m working on a piece of code that checks if stdin represents a directory and, if it does, performs some operations on it

Currently, I have code that works on Unix systems:

let fd = stdin().as_fd().try_clone_to_owned().unwrap();
let file = File::from(fd);
let meta = file.metadata().unwrap();
if meta.is_dir() {
   let mut stdin_path = fs::canonicalize("/dev/stdin").unwrap();
   println!({:?}", stdin_path);
   // do something    
}

I’m trying to ensure it works on Windows as well. Since Windows doesn’t have std::os::fd::AsFd , as_fd methods, plus there’s no /dev/stdin, I’m not sure about the appropriate APIs to use to achieve the same functionality on Windows. Any guidance to make it work on Windows?
