<p>If you want to implement your own, custom defragmentation algorithm, there is infrastructure prepared for that, but it is not exposed through the library API - you need to hack its source code. Here are steps needed to do this:</p>
<ol type="1">
<li>Main thing you need to do is to define your own class derived from base abstract class <code>VmaDefragmentationAlgorithm</code> and implement your version of its pure virtual methods. See definition and comments of this class for details.</li>
<li>Your code needs to interact with device memory block metadata. If you need more access to its data than it's provided by its public interface, declare your new class as a friend class e.g. in class <code>VmaBlockMetadata_Generic</code>.</li>

<li>Modify function <code>VmaBlockVectorDefragmentationContext::Begin</code> to create object of your new class whenever needed. </li>
