Bug NetCode seems to be generating an empty serializer for longs?

This code seems to cause NetCode to generate an empty serializer, despite deleting the folder and clicking "Build" through the code generation wizard.

Code (CSharp):

1. public struct MoveClientToServerRpcCommand : IRpcCommand
2. {
3.     public long X;
4.     public long Y;
5.     public long Z;
6. }

Code (CSharp):

1. namespace Assembly_CSharp.Generated
2. {
3.     [BurstCompile]
4.     public struct MoveClientToServerRpcCommandSerializer : IComponentData, IRpcCommandSerializer<MoveClientToServerRpcCommand>
5.     {
6.         public void Serialize(ref DataStreamWriter writer, in RpcSerializerState state, in MoveClientToServerRpcCommand data)
7.         {
8.         }
9.  
10.         public void Deserialize(ref DataStreamReader reader, in RpcDeserializerState state,  ref MoveClientToServerRpcCommand data)
11.         {
12.         }

Receiving system

Code (CSharp):

1. [UpdateInGroup(typeof(ServerSimulationSystemGroup))]
2. public class MoveRpcCommandServerSystem : ComponentSystem
3. {
4.     protected override void OnUpdate()
5.     {
6.         Entities
7.             .ForEach((Entity entity, ref MoveClientToServerRpcCommand cmd, ref ReceiveRpcCommandRequestComponent req) =>
8.             {
9.                 PostUpdateCommands.DestroyEntity(entity);
10.                 var group = World.GetExistingSystem<GhostPredictionSystemGroup>();
11.                 var broadcast = PostUpdateCommands.CreateEntity();
12.                 Debug.Log($"[SERVER] Received {cmd.X}, {cmd.Y}, {cmd.Z}");
13.                 Debug.Log($"[SERVER] Received {new fp3( fp.FromRaw(cmd.X), fp.FromRaw(cmd.Y), fp.FromRaw(cmd.Z) )}");
14.                 PostUpdateCommands.AddComponent(broadcast, new MoveServerToClientRpcCommand
15.                 {
16.                     Tick = group.PredictingTick,
17.                     X = cmd.X,
18.                     Y = cmd.Y,
19.                     Z = cmd.Z
20.                 });
21.                 PostUpdateCommands.AddComponent(broadcast, new SendRpcCommandRequestComponent());
22.             });
23.     }
24. }

 

Ah there's no bug, they just have to be transmitted as ulongs
