QuickBin

QuickBin is intended to make binary serialization and deserialization nearly thoughtless.

Serialization and deserialization are made to be mirror images of each other, so it's easy to see what you're doing, and make sure you serialize and deserialize your data the exact same way. The heavy focus on method chaining makes it easy to read, and quick to implement.

Unity Installation

To install QuickBin, go to the package manager, press the plus button in the top left, select Add package by git URL... and enter https://github.com/abledbody/QuickBin.git

The Serializer class

The serializer is a wrapper for a List<byte>. Each time you call Serializer.Write it picks the appropriate overload method for the provided type, and adds the bytes to the list. Once you're ready to use the produced bytes, like to write them to a file, you can simply put the reference to the serializer into an argument or field of type byte[], and it will implicitly convert itself.

var helloWorld = "Hello, QuickBin!";

var buffer = new Serializer()
  .Write(10)
  .Write(18.5f)
  .Write(helloWorld, Serializer.Len_u16);

byte[] bytes = buffer;

The Deserializer class

The deserializer is primarily a wrapper around a byte[] buffer, with an int ReadIndex, an int ForbiddenIndex. The deserializer will never mutate the byte array, and can effectively only read between ReadIndex and ForbiddenIndex. Every time you call Deserializer.Read, ReadIndex will increment by the number of bytes read for the specified type. If you attempt to read data beyond the end of the buffer, or beyond ForbiddenIndex, it will stop producing meaningful data, and Deserializer.Overflowed will be set to true.

Each overload for Deserializer.Read provides an out argument. Using initialization syntax or providing an existing typed field is how the deserializer selects the correct overload method for converting bytes into a type.

new Deserializer(bytes)
  .Read(out int firstNumber)
  .Read(out float secondNumber)
  .Read(out helloWorld, Deserializer.Len_u16);

Debug.Log($"firstNumber: {firstNumber}, secondNumber: {secondNumber}, helloWorld: {helloWorld}");

Custom extensions

Extending the serializer and deserializer is fairly easy. Just make a static class (I recommend it also be partial) and write a Write method for Serializer, and a Read method for Deserializer.

public static partial class QuickBinExtensions {
  public static Serializer Write(this Serializer buffer, ExampleClass value) => buffer
    .Write(value.foo)
    .Write(value.bar);
  
  public static Deserializer Read(this Deserializer buffer, out ExampleClass produced) => buffer
    .Read(out int foo)
    .Read(out double bar)
    .Validate(() => new(foo, bar), out produced);
}
