Non-JSON evaluation targets

[Horusiath]

Hi, I'm trying to use this project to introduce some JSON Path support for other (non-serde-json) document-tree formats. It would be great if this library could work as a foundation for evalution of formats like ie. CBOR or document-like DBs.

Currently it's not possible to build your own query evaluator using this library. The bare minimum requires access to whole parse tree of JsonPath including ie. pattern match over JsonPathIndex/Function which are not part of the public API (jsonpath_rust::model is pub(crate)).

Another idea would be to introduce a generic trait to simplify evaluation model - given implementations for methods such as iterate / access-by-field / access-by-index etc. - which are specific to target tree-type we're querying over - I think the whole JSON Path query evaluation could be made pretty generic.

Hi!
Have you had a look into JsonLike trait?

Do you think it is what you need?
