in a single VkDeviceMemory block.

bool Validate ()

Validates all data structures inside this object. If not valid, returns false.

size_t GetAllocationCount ()
VkDeviceSize GetSumFreeSize ()
VkDeviceSize GetUnusedRangeSizeMax ()
bool IsEmpty ()

Returns true if this block is empty - contains only single free suballocation.

void CalcAllocationStatInfo (VmaStatInfo & outInfo)
void AddPoolStats (VmaPoolStats & inoutStats)

Shouldn't modify blockCount.

void PrintDetailedMap (class VmaJsonWriter & json)
bool CreateAllocationRequest (uint32_t currentFrameIndex, uint32_t frameInUseCount, VkDeviceSize bufferImageGranularity, VkDeviceSize allocSize, VkDeviceSize allocAlignment, bool upperAddress, VmaSuballocationType allocType, bool canMakeOtherLost, uint32_t strategy, VmaAllocationRequest * pAllocationRequest)

Tries to find a place for suballocation with given parameters inside this block.

If succeeded, fills pAllocationRequest and returns true.

If failed, returns false.

VkResult CheckCorruption (const void * pBlockData)
void Alloc (const VmaAllocationRequest & request, VmaSuballocationType type, VkDeviceSize allocSize, VmaAllocation hAllocation)

Makes actual allocation based on request. Request must already be checked and valid.

void Free (const VmaAllocation allocation)

Frees suballocation assigned to given memory region.
