I might be wrong, but it seems there's an issue here:

fn walk_dir(path: &Path) -> std::io::Result<()> {
    for entry in path.read_dir()? {
        if let Ok(entry) = entry {
            if entry.path().is_file() {
                do_stuff_on_file(&entry.path())?;
            } else if entry.path().is_dir() {
                walk_dir(&entry.path())?;
            }
        }
    }
    Ok(())
}
