You can defragment a specific custom pool by setting VmaDefragmentationInfo::pool Although functions like vmaCreateBuffer(), vmaCreateImage(), vmaDestroyBuffer(), vmaDestroyImage()
(like in the example above) or all the default pools by setting this member to null. create/destroy an allocation and a buffer/image at once, these are just a shortcut for
creating the resource, allocating memory, and binding them together.
Defragmentation works on memory allocations only. You must handle the rest manually.
Defragmentation is an iterative process that should repreat "passes" as long as related functions
return `VK_INCOMPLETE` not `VK_SUCCESS`.
In each pass:
1. vmaBeginDefragmentationPass() function call:
- Calculates and returns the list of allocations to be moved in this pass.
Note this can be a time-consuming process.
- Reserves destination memory for them by creating internal allocations.
Returns their `VkDeviceMemory` + offset.
2. Inside the pass, **you should**:
- Inspect the returned list of allocations to be moved.
- Create new buffers/images and bind them at the returned destination `VkDeviceMemory` + offset.
- Copy data from source to destination resources if necessary.
- Destroy the source buffers/images, but NOT their allocations.
3. vmaEndDefragmentationPass() function call:
- Frees the source memory reserved for the allocations that are moved.
- Modifies #VmaAllocation objects that are moved to point to the destination reserved memory.
- Frees `VkDeviceMemory` blocks that became empty.
Unlike in previous iterations of the defragmentation API, there is no list of "movable" allocations passed as a parameter. Unlike in previous iterations of the defragmentation API, there is no list of "movable" allocations passed as a parameter.

If you cannot ensure any allocation can be moved, it is better to keep movable allocations separate in a custom pool. If you cannot ensure any allocation can be moved, it is better to keep movable allocations separate in a custom pool.
You can also decide to destroy an allocation instead of moving it. Inside a pass, for each allocation that should be moved:
You should then set `pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_DESTROY.
- You should copy its data from the source to the destination place by calling e.g. `vkCmdCopyBuffer()`, `vkCmdCopyImage()`.
- You need to make sure these commands finished executing before destroying the source buffers/images and before calling vmaEndDefragmentationPass().
- If a resource doesn't contain any meaningful data, e.g. it is a transient color attachment image to be cleared,
filled, and used temporarily in each rendering frame, you can just recreate this image
without copying its data.
- If the resource is in `HOST_VISIBLE` and `HOST_COHERENT` memory, you can copy its data on the CPU
using `memcpy()`.
- If you cannot move the allocation, you can set `pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_IGNORE.
This will cancel the move.
- vmaEndDefragmentationPass() will then free the destination memory
not the source memory of the allocation, leaving it unchanged.
- If you decide the allocation is unimportant and can be destroyed instead of moved (e.g. it wasn't used for long time),
you can set `pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_DESTROY.
- vmaEndDefragmentationPass() will then free both source and destination memory, and will destroy the #VmaAllocation object.
You can defragment a specific custom pool by setting VmaDefragmentationInfo::pool
(like in the example above) or all the default pools by setting this member to null.
Defragmentation is always performed in each pool separately.
Allocations are never moved between different Vulkan memory types.
The size of the destination memory reserved for a moved allocation is the same as the original one.
Alignment of an allocation as it was determined using `vkGetBufferMemoryRequirements()` etc. is also respected after defragmentation.
Buffers/images should be recreated with the same `VkBufferCreateInfo` / `VkImageCreateInfo` parameters as the original ones.
