Subvolume iterator info

This example requires elevated privileges.

// This will print out informations about all subvolumes under /

// Retrieve the subvolume for /
let root_subvol = Subvolume::get("/").unwrap();

// Retrieve a subvolume iterator for /
let subvol_iterator: SubvolumeIterator = {
    let result: Result<SubvolumeIterator> = root_subvol.into();
    result.unwrap()
};

// Iterate over the subvolumes and print out their debug information
for subvolume in subvol_iterator {
    println!("{:?}", subvolume.info().unwrap());
}
