rdiff = "0.1"

In your rust file (taken from examples/predefined.rs):

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<_>>());
}

This will output

Inserts: [Insert(8, 'widely understood '), Insert(90, ' absolutely'), Insert(381, 'hters, or sons if the family was progressive.\n'), Insert(572, 'not, even though he had been following the news quite closely.\n\n'), Insert(734, '\nMr. Ben')]
Deletes: [Delete(34, 24), Delete(428, 8), Delete(638, 8), Delete(742, 8)]
