Struct vk_mem_alloc::ffi::VmaDetailedStatistics

#[repr(C)]
pub struct VmaDetailedStatistics {
    pub statistics: VmaStatistics,
    pub unusedRangeCount: u32,
    pub allocationSizeMin: DeviceSize,

\brief 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:

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

Fields

statistics: VmaStatistics

Basic statistics.

unusedRangeCount: u32

Number of free ranges of memory between allocations.

allocationSizeMin: DeviceSize

Smallest allocation size. VK_WHOLE_SIZE if there are 0 allocations.

allocationSizeMax: DeviceSize

Largest allocation size. 0 if there are 0 allocations.

unusedRangeSizeMin: DeviceSize

Smallest empty range size. VK_WHOLE_SIZE if there are 0 empty ranges.

unusedRangeSizeMax: DeviceSize

Largest empty range size. 0 if there are 0 empty ranges.
