Hi I am trying to implement a dynamic API. I have followed the suggestions in https://groups.google.com/g/capnproto/c/Ivl3u4JJoEQ/m/MIH2a2nPBQAJ and https://groups.google.com/g/capnproto/c/fNnr3Om9haM/m/1TdBqwsNBwAJ
My implementation attempt lies at https://github.com/DaneSlattery/capnp_generic_poc . The desired data flow is as follows: 1. A client connects to a server, and receives a capability that allows the client to load a schema (the InterfaceLoader). When connecting, the client also passes a ClientInterface to the server. 2. The client registers a schema using the InterfaceLoader. The client must send a Schema.Node parameter to the server. The server must load the schema. 3. The server uses the given loaded schema to communicate with the client interface, which takes a parameter of AnyStruct. I have a few problems: Firstly, when the client attempts to set the schema using capnp::Schema::from<Message>().getProto() , line 683 of capnproto-c++-0.10.3/src/capnp/dynamic.c++ blows up. I have changed this line to, instead assessing the ID of the schema for equality : KJ_REQUIRE(structValue.getSchema().getProto().getId() == structType.getProto().getId(), "Value type mismatch.") { return; } I think this change should perhaps go in a PR, unless there is another, better way. Secondly, I can't figure out how to send messages of the loaded schema back from the server to the client. Can anyone see if the POC linked is viable, and how to get to the final step? - Dane -- You received this message because you are subscribed to the Google Groups "Cap'n Proto" group.
