Inside this function we find ## public void encode(ByteBuf var1x, T var2) { ## int var3 = var1.applyAsInt(var2); ## VarInt.write(var1x, var3); ## } ## which as we can see writes the varint to the buffer. ## If you want to see all the serializers try regexp searching "StreamCodec.*Particle" data: type ?
