Required methods

fn handle_request<Query, Mutation, Subscription>(
    &mut self,
    schema: &Schema<Query, Mutation, Subscription>,
    stubs: &mut SubscriptionStubs<Query, Mutation, Subscription>,
    data: Bytes
) -> Result<Option<Bytes>, Self::Error> where
    Query: ObjectType + Sync + Send + 'static,
    Mutation: ObjectType + Sync + Send + 'static,
    Subscription: SubscriptionType + Sync + Send + 'static, 

Parse the request data here. If you have a new request, create a SubscriptionStub with the Schema::create_subscription_stub, and then call SubscriptionStubs::add. You can return a Byte, which will be sent to the client. If it returns an error, the connection will be broken.

fn handle_response(&mut self, id: usize, result: Result<Value>) -> Option<Bytes>

When a response message is generated, you can convert the message to the format you want here.
