Two possibilities, either use a wrapper struct:

    string toString() const { return value.toString(); }
    static UUID fromString(string str) { return UUID(str); }
}

assert(uuid.serializeToJson() == Json(uuid.toString()));

or use the serialization policy feature: 

template Policy(T) if (is(T == UUID)) {
    static string toRepresentation(UUID value) { return value.toString(); }
    static UUID fromRepresentation(string str) { return UUID(str); }
}

assert(uuid.serializeWithPolicy!(JsonSerializer, Policy) == Json(uuid.toString());

Hi,

the wrapper seems a bit clunky for my case, but I like the serialization policy. However, I am not sure, how to use the policy with the Rest interface generator.

Suppose I have this code: 

struct SomeIDs
{
  UUID id1,
  UUID id2
}

interface API
{
  @property someIDs getIDs();
}

class RestServer : API
{
  private URLRouter _router;
  public:
    this() {
      _router = new URLRouter();
      _router.registerRestInterface(this, MethodStyle.camelCase);
    }
  ...
}

Where do I apply the policy?

Thanks,
Martin
