Serializing mixed type arrays with protobuf

[Flo Loferer]

I have an array containing two different object types.

Is there a chance to serialize this array with protobuf?

What would the message definition look like?

If you want an array of mixed-type data, the best option in protobuf is something like this:

message Types {

  oneof types {

    Foo foo = 1;

    Bar bar = 2;

  }

}

message Container {

  repeated Types list = 1;
