Function patch_unsafe

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

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.

ยงExample

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" }
]));
