VmaDetailedStatistics Struct Reference

More detailed statistics than VmaStatistics. More...

#include <vk_mem_alloc.h>

Public Attributes
VmaStatistics	statistics
	Basic statistics.
uint32_t	unusedRangeCount
	Number of free ranges of memory between allocations.
VkDeviceSize	allocationSizeMin
	Smallest allocation size. VK_WHOLE_SIZE if there are 0 allocations.
VkDeviceSize	allocationSizeMax
	Largest allocation size. 0 if there are 0 allocations.
VkDeviceSize	unusedRangeSizeMin
	Smallest empty range size. VK_WHOLE_SIZE if there are 0 empty ranges.
VkDeviceSize	unusedRangeSizeMax
	Largest empty range size. 0 if there are 0 empty ranges.

Detailed Description

More detailed statistics than VmaStatistics.

These are slower to calculate. Use for debugging purposes. See functions: vmaCalculateStatistics(), vmaCalculatePoolStatistics().

Previous version of the statistics API provided averages, but they have been removed because they can be easily calculated as:

VkDeviceSize allocationSizeAvg = detailedStats.statistics.allocationBytes / detailedStats.statistics.allocationCount;
VkDeviceSize unusedBytes = detailedStats.statistics.blockBytes - detailedStats.statistics.allocationBytes;
VkDeviceSize unusedRangeSizeAvg = unusedBytes / detailedStats.unusedRangeCount;
