Calculated statistics of memory usage e.g. in a specific memory type, heap, custom pool, or total.
These are fast to calculate. See functions: vmaGetHeapBudgets(), vmaGetPoolStatistics().
| VkDeviceSize VmaStatistics::allocationBytes |
Total number of bytes occupied by all VmaAllocation objects.
Always less or equal than blockBytes. Difference (blockBytes - allocationBytes) is the amount of memory allocated from Vulkan but unused by any VmaAllocation.
| uint32_t VmaStatistics::allocationCount |
Number of VmaAllocation objects allocated.
Dedicated allocations have their own blocks, so each one adds 1 to allocationCount as well as blockCount.
| VkDeviceSize VmaStatistics::blockBytes |
Number of bytes allocated in VkDeviceMemory blocks.
VkDeviceMemory object (e.g. as in VkPhysicalDeviceLimits::maxMemoryAllocationCount) is called a "block" in VMA, while VMA calls "allocation" a VmaAllocation object that represents a memory region sub-allocated from such block, usually for a single buffer or image.
