Oops, I meant to point you to google.protobuf.Value: https:/ /github.com/google/protobuf/blob/master/src/google/protobuf/struct.proto#L63

The Struct type is what is used to represent JSON *objects* (there is also ListValue, for arrays, as well as support for JS primitive types and null). ---- *Josh Humphries* jh...@bluegosling.com On Thu, Jun 21, 2018 at 3:25 PM, Josh Humphries <jh...@bluegosling.com> wrote: > Hi, John, > Take a look at the well-known type google.protobuf.Struct.
