    JSON Patch

    This library implements [RFC 6902](https://tools.ietf.org/html/rfc6902 RFC6902), JSON Patch (and RFC 6901, JSON Pointer) for Elm.

    Usage

    Let's say you previously have gotten a JSON document as a Value from the server or via a port. Now you get a Value that is a JSON Patch for that document.

    newDocument =
        Json.Decoder.decodeValue Json.Patch.decoder patch
            |> Result.andThen (\p -> Json.Patch.apply p document)
    

    Patching needs to be done on the Value type, due to the type system (records can't be accessed by field name in Elm).

    However, if you have an encoder/decoder pair for your Elm type, you can patch the Elm type like this:

    newElmData =
        Json.Decoder.decodeValue Json.Patch.decoder patch
            |> Result.andThen
                (\p ->
                    dataEncoder elmData
                        |> Json.Patch.apply p
                        |> Result.andThen (Json.Decoder.decodeValue dataDecoder)
                )
