Function move_command_line_common::files::find_filenames

pub fn find_filenames<Predicate: FnMut(&Path) -> bool>(
    paths: &[impl AsRef<Path>],
    is_file_desired: Predicate
) -> Result<Vec<String>>

• For each directory in paths, it will return all files that satisfy the predicate
• Any file explicitly passed in paths, it will include that file in the result, regardless of the file extension
