Crate jatch

A crate to provide a fast, correct and safe implementation of JSON Patch (RFC 6902)

It can apply patches to JSON documents:

let doc = json!({"hello": "world"});
let patch = Patch::Add {
    path: Path::new("/foo"),
    value: json!("bar"),
};
assert_eq!(
    apply(doc, vec![patch]).unwrap(), 
    json!({
        "hello": "world",
        "foo": "bar",
    })
);

It can also calculate the diffs between 2 JSONs:

let patches = diff(
  json!({"hello": "world"}),  
  json!({"hello": "world", "foo": "bar"}),
);
assert_eq!(
    patches[0], 
    Patch::Add {
      path: Path::new("/foo"),
      value: json!("bar"),
    }
);
