Examples

Create and patch document using JSON Patch:

use serde_json::{from_value, json};

let mut doc = json!([
    { "name": "Andrew" },
    { "name": "Maxim" }
]);

let p: Patch = from_value(json!([
  { "op": "test", "path": "/0/name", "value": "Andrew" },
  { "op": "add", "path": "/0/happy", "value": true }
])).unwrap();

patch(&mut doc, &p).unwrap();
assert_eq!(doc, json!([
  { "name": "Andrew", "happy": true },
  { "name": "Maxim" }
]));

Create and patch document using JSON Merge Patch:

#[macro_use]
use json_patch::merge;
use serde_json::json;

let mut doc = json!({
  "title": "Goodbye!",
  "author" : {
    "givenName" : "John",
    "familyName" : "Doe"
  },
  "tags":[ "example", "sample" ],
  "content": "This will be unchanged"
});

let patch = json!({
  "title": "Hello!",
  "phoneNumber": "+01-123-456-7890",
  "author": {
    "familyName": null
  },
  "tags": [ "example" ]

merge(&mut doc, &patch);
assert_eq!(doc, json!({
