Public Attributes
UINT	BlockCount
	Number of D3D12 memory blocks allocated - ID3D12Heap objects and committed resources.
UINT	AllocationCount
	Number of D3D12MA::Allocation objects allocated. More...
UINT64	BlockBytes
	Number of bytes allocated in memory blocks.
UINT64	AllocationBytes
	Total number of bytes occupied by all D3D12MA::Allocation objects. More...

Detailed Description

Calculated statistics of memory usage e.g. in a specific memory heap type, memory segment group, custom pool, or total.

These are fast to calculate. See functions: D3D12MA::Allocator::GetBudget(), D3D12MA::Pool::GetStatistics().

Member Data Documentation

AllocationBytes

UINT64 D3D12MA::Statistics::AllocationBytes

Total number of bytes occupied by all D3D12MA::Allocation objects.

Always less or equal than BlockBytes. Difference (BlockBytes - AllocationBytes) is the amount of memory allocated from D3D12 but unused by any D3D12MA::Allocation.

AllocationCount

UINT D3D12MA::Statistics::AllocationCount

Number of D3D12MA::Allocation objects allocated.

Committed allocations have their own blocks, so each one adds 1 to AllocationCount as well as BlockCount.
