json-toolkit

The json-toolkit crate exposes all the common manipulation/validation operation expected from a JSON pointer and support several JSON value representation :

• Encode RFC6901 representation in Pointer type.
• Manipulate any JSON value by a JSON pointer.

use json_toolkit::{ValueExt, Pointer};
use serde_json::{Value, json};

let mut json = json!({ "foo": "bar", "zoo": { "id": 1 } });

json.insert_at(&Pointer::new("/zoo/new_field").unwrap(), "new_value").unwrap();
assert_eq!(json, json!({ "foo": "bar", "zoo": { "id": 1, "new_field": "new_value" } }));

let old_value = json.insert("foo".to_string(), 42).unwrap();
assert_eq!(old_value, Some("bar".into()));
assert_eq!(json, json!({ "foo": 42, "zoo": { "id": 1, "new_field": "new_value" } }));

let id = ValueExt::pointer(&json, &Pointer::new("/zoo/id").unwrap());
assert_eq!(id, Some(&1.into()));

Features

json-toolkit supports several JSON value representation, and has features that may be enabled or disabled :

• serde: Enable serde {de}serialization on Pointer type and implement ValueExt on serde_json::Value type.
• json: Implement ValueExt on json::JsonValue type.
