Your usage and implementation of get_files_in_dir is quite awkward. It is returning None on errors and then you’re returning Ok(()) when it returns None, ignoring a bunch of errors. Why not just have get_files_in_dir return a Result<Vec<PathBuf>, io::Error>? You could drastically simplify the function by just ?ing the results.
