I’m currently trying to implement the Java Edition Server protocol, starting with the data types (like Boolean, VarInt, BitSet, Slot) and transfering them via tcp packets. I’m trying to make it type-safe via a Transferable trait (as seen below) that a few newtypes (respectively called VarInt, Boolean etc) which can be sent over will implement, so I can later just put some of these together for actually implementing the protocol without having to worry about the low-level details (= I can just do sth like send(stream, [VarInt(45), Byte])). I hope this accelerates the implementation.
