Function fs_utils::copy::copy_directory

pub fn copy_directory<P, O>(
    source_dir: P, 
    destination_dir: O
) -> Result<PathBuf, Error> where
    P: AsRef<Path>,
    O: AsRef<Path>, 

Copies the contents of the source directory to the given destination directory. In destination_dir, a new subdirectory with the basename of the source_dir will be created. It will not perform the copy operation if the effective destination directory does already exist.

The returned value will contain a copied directory's path.
