      ## ## Tips for reviewing particle data (as of 1.20.5)
      ## Inside the registry code, each particle can have an associated "options" type and
      ## each options type can add additional data to be encoded.
      ## For example, this line
      ##    public static final ParticleType<BlockParticleOption> BLOCK = register("block", false, BlockParticleOption::codec, BlockParticleOption::streamCodec);
      ## will read the stream codec from BlockParticleOption.java's streamCodec member; then we see
      ##       return ByteBufCodecs.idMapper(Block.BLOCK_STATE_REGISTRY).map(var1 -> new BlockParticleOption(var0, var1), var0x -> var0x.state);
      ## this encodes with the ByteBufCodecs.idMapper function. 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"
