Vec Slices with pointer?

[naterichman]

Still fairly new to rust so apologies if I'm misunderstanding and/or using lingo wrong.

Looking at the code for pointer it doesn't seem like it would support slices, i.e.

{
    "test": {
        "test2": [
            "a",
            "b",
            "c"
        ]
    }
}

I'd like to do something like: /test/test2/0..2 and also support nested structures. I've been trying to implement this myself (somewhat as a learning exercise, but also it would be useful), but I'm getting stuck on Value::Array needing owned values. I tried modifying the pointer function:

       pointer
            .split('/')
            .skip(1)
            .map(|x| x.replace("~1", "/").replace("~0", "~"))
            .try_fold(self, |target, token| match target {
                Value::Object(map) => map.get(&token),
                Value::Array(list) => {
                    let val = parse_index(&token).and_then(|x| list.get(x));
                    if val.is_some() {
                        return val
                   } else {
                        return Some(&parse_range(&token)
                            .and_then(|range| Value::from(&list[range]))
                        )
                },
                _ => None,
            })

But I get a dangling reference. I understand why I get it, but I can't figure out a way around it. Would appreciate some guidance on how I'm approaching this, thanks in advance!
