Function json_patch::patch_unsafe

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

Patch provided JSON document (given as serde_json::Value) in-place. Different from patch if any patch failed, the document is left in an inconsistent state. In case of internal error resulting in panic, document might be left in inconsistent state.

Example

Create and patch document:

#[macro_use]
use json_patch::{Patch, patch_unsafe};
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_unsafe(&mut doc, &p).unwrap();
assert_eq!(doc, json!([
  { "name": "Andrew", "happy": true },
  { "name": "Maxim" }
]));
