feat: jsonpath experimental support

[zxch3n]

Example

It's gated by a feature in Rust crate and cannot be used in WASM at the moment

fn setup_test_doc() -> LoroDoc {
    let doc = LoroDoc::new();
    let store = doc.get_map("store");

    let books = store.insert_container("book", LoroList::new()).unwrap();
    books
        .insert_container(
            0,
            create_map_from_json(json!({
                "category": "reference",
                "author": "Nigel Rees",
                "title": "Sayings of the Century",
                "price": 8.95,
                "isbn": "0-553-21311-3"
            })),
        )
        .unwrap();
    books
        .insert_container(
            1,
            create_map_from_json(json!({
                "category": "fiction",
                "author": "Evelyn Waugh",
                "title": "Sword of Honour",
                "price": 12.99,
                "isbn": "0-553-21312-1"
            })),
        )
        .unwrap();
    books
        .insert_container(
            2,
            create_map_from_json(json!({

        )
        .unwrap();
    books
        .insert_container(
            3,
            create_map_from_json(json!({
                "category": "fiction",
                "author": "J. R. R. Tolkien",
                "title": "The Lord of the Rings",
                "price": 22.99,
                "isbn": "0-395-19395-8"
            })),
        )
        .unwrap();

    store
        .insert_container(
            "bicycle",
            create_map_from_json(json!({
                "color": "red",
                "price": 19.95
            })),
        )
        .unwrap();

    store.insert("expensive", 10).unwrap();

    doc
}

#[test]
fn test_all_authors() -> anyhow::Result<()> {
    let doc = setup_test_doc();
    let ans = doc.jsonpath("$.store.book[*].author")?;
    assert_eq!(
        to_json(ans),
        json!([
            "Nigel Rees",
            "Evelyn Waugh",
            "Herman Melville",
            "J. R. R. Tolkien"
        ])
    );
    Ok(())
}

Is all the syntax the same as jsonpath?

In the current supported subset, yes
