Modifying returned by query values

[robert-mac-wbt]

Hello 👋

I wanted to ask if it's possible to do something following with this crate.
I want to be able to run multiple queries on some JSON to eventually find a node that I'd like to modify/remove.
In the following example, I'm trying to remove the genre of the second book from the list.

use std::str::FromStr;
use serde_json::{Value};
use jsonpath_rust::{JsonPathFinder, JsonPathInst, JsonPathQuery};

fn main() {
    let data = r#"
    {
        "books": [
            {
                "title": "Title 1",
                "details": {
                    "description": "Description 1",
                    "genre": "Genre 1"
                }

            },
            {
                "title": "Title 2",
                "details": {
                    "description": "Description 2",
                    "genre": "Genre 2"
                }
            }
        ]
    }
  "#;

    let json: Value = serde_json::from_str(data).unwrap();
    let books_path = JsonPathInst::from_str("$.books").unwrap();
    let finder = JsonPathFinder::new(Box::from(json), Box::new(books_path)); // had to clone due to ownership

    let books = finder.find_slice().get(0).unwrap().clone().to_data();

    let second_book = books.get(1).unwrap();
    let genre_value = second_book.clone().path("$.details.genre").unwrap(); // had to clone due to ownership in path

    // remove genre_value
}

Do you have any suggestion how to achieve this?
If I'm not mistaken find returns new Values and find_slice return reference to the Value. However none of them return mutable reference, maybe adding it could help with this?
Or maybe once the feature mentioned in #31 is added I could find the paths that are to be removed/modified, clone whole "original" json and modify it using these paths 🤔
If you have any other idea please point me to the right direction 🙏

Thanks!

Hi!
It seems the issue is connected to that one #12.

Yeah, it seems, the existing API does not allow doing that.
We need to add the mutable ref.

I will look into it in a couple of weeks apparently.
