extern crate rdiff;
use rdiff::BlockHashes;
use std::fs::File;
pub fn example() {
let file = File::open("examples/filev1.txt").unwrap();
let mut hashes = BlockHashes::new(file, 8).unwrap();
let file = File::open("examples/filev2.txt").unwrap();
let difference = hashes.diff_and_update(file).unwrap();
println!("Inserts: {:?}", difference.inserts().collect::<Vec<_>>());
println!("Deletes: {:?}", difference.deletes().collect::<Vec<_>>());
}
