 A JSONPath library for rust. The idea behind this library is that it can operate on any json representation as long as it implements the [`SelectValue`](src/select_value.rs) triat. The library has an implementation for [serde_json value](https://docs.serde.rs/serde_json/value/enum.Value.html) and [ivalue](https://docs.rs/tch/0.1.1/tch/enum.IValue.html).
