Convert ygot diff output to JSON IETF

[adelshafiei]

I am working with a gNMI server which only supports JSON IETF encodings. So I am trying to convert the output of ygot diff API to JSON IETF Encodings:

type TypedValue struct {
// One of the fields within the val oneof is populated with the value
// of the update. The type of the value being included in the Update
// determines which field should be populated. In the case that the
// encoding is a particular form of the base protobuf type, a specific
// field is used to store the value (e.g., json_val).
//
// Types that are assignable to Value:
// *TypedValue_StringVal
// *TypedValue_IntVal
// *TypedValue_UintVal
// *TypedValue_BoolVal
// *TypedValue_BytesVal
// *TypedValue_FloatVal
// *TypedValue_DecimalVal
// *TypedValue_LeaflistVal
// *TypedValue_AnyVal
// *TypedValue_JsonVal
// *TypedValue_JsonIetfVal
// *TypedValue_AsciiVal
// *TypedValue_ProtoBytes
Value isTypedValue_Value protobuf_oneof:"value"
// contains filtered or unexported fields
}

Is there an API that gets TypedValue of different formats and converts them to JSON IETF?

Thanks,

Unforunately I don't think there is a function that converts TypedValue to JSON, even if all of these are leafs.

One way is to unmarshal these one-by-one back into a GoStruct using ytypes' SetNode, and then getting each value via GetNode, and then calling ygot.Marshal7951.

Another way is to unmarshal all of them into a GoStruct using ytypes' SetNode, and then simply calling ygot.Marshal7951 that gives you a bigger piece of JSON.

Another way is to add to the implementation a new DiffOpt for ygot.Diff that encodes the values using Marshal7951 instead of EncodeTypedValue.
