Function patience_diff::patience_diff

pub fn patience_diff<'a, T>(a: &'a [T], b: &'a [T]) -> Vec<DiffComponent<&'a T>> where
    T: Eq + Hash, 

Computes the patience diff betwen a and b. The DiffComponents hold references to the elements in a and b they correspond to.

use patience_diff::DiffComponent;

let a: Vec<_> = "AaaxZ".chars().collect();
let b: Vec<_> = "AxaaZ".chars().collect();

let diff = patience_diff::patience_diff(&a, &b);
