Refactoring Pointer

Refactoring Pointer Struct

Features

Create an empty pointer can now be like this:

Pointer pointer = Pointer.Empty;

Pointer equality comparer:

Pointer pointerA = new Pointer(1, 2, 45, true);
Pointer pointerB = new Pointer(1, 2, 45, true);

pointerA == pointerB;   // true

Pointer Superposition

Pointer pointerA= new Pointer(1, 2, 45, true);
Pointer pointerB = new Pointer(2, 3, 45, true);

var mulPointer = pointerA * pointerB;
var divpointer = mulPointer / pointerB;

divpointer == pointerA;   // true

UnitTests Passed

Adding UnitTest for serializing and deserializing Pointer

[Test]
public void Created_Pointer_Can_Be_Serialized_As_Json_And_Deserialized_Back()
{
    Pointer pointerA = new Pointer(1, 2, 45, true);

    // this option is just to make the json formatting pretty
    // and able to convert Pointer struct using custom converter
    var jsonOption = new JsonSerializerOptions { WriteIndented = true };
    jsonOption.Converters.Add(new PointerJsonConverter());

    // first, serialize Pointer as json string
    var json = JsonSerializer.Serialize(pointerA, jsonOption);
    TestContext.WriteLine("Output pointerA as Json");
    TestContext.WriteLine(json);

    // second, deserialize json string back to pointer
    var pointerB = JsonSerializer.Deserialize<Pointer>(json, jsonOption);

    // the result should be equal Pointer
    Assert.AreEqual(pointerA, pointerB);
}

The output:
