Function patch 

pub fn patch(
    doc: &mut Value,
    patch: &[PatchOperation],
) -> Result<(), PatchError>

Patch provided Platform Value document (given as platform_value::Value) in-place. If any of the patch is failed, all previous operations are reverted. In case of internal error resulting in panic, document might be left in inconsistent state.

Example

Create and patch document:

#[macro_use]
use platform_value::{Patch, patch, from_value, platform_value};

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

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

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