Hello,
using cap'n'proto c++ library, I've made a structure for generic request
exchange
struct Request {
timestamp @0: UInt64;
resource @1: Text;
payload @2: AnyPointer;
}
resource used for the request name, and payload for the request argument.
I successfully used it with custom structure inside the payload, but I
can't figure out how I can put simple Text in the payload
::capnp::MallocMessageBuilder message;
Request::Builder req = message.initRoot<Request>();
req.setTimestamp(timestamp_now());
req.setResource("MyRequest");
and now I would like to init the payload and put text in it. I tried
something like that
auto payload_text = req.getPayload().initAs<Text>();
gives me
error: too few arguments to function call, expected 2, have 1
return _::PointerHelpers<T>::init(builder);
auto payload_text = req.getPayload().getAs<Text>();
compile, but then I cannot change the text in payload_text
I couldn't find any sample where AnyPointer is used with Text. Any clue ?
Best regards,
William
