Here are the classes, structs, unions and interfaces with brief descriptions:

[detail level 12]

▼ND3D12MA
CAllocation	Represents single memory allocation
CALLOCATION_CALLBACKS	Custom callbacks to CPU memory allocation functions
CALLOCATION_DESC	Parameters of created D3D12MA::Allocation object. To be used with Allocator::CreateResource
CAllocator	Represents main object of this library initialized for particular `ID3D12Device`
CALLOCATOR_DESC	Parameters of created Allocator object. To be used with CreateAllocator()
CBudget	Statistics of current memory usage and available budget for a specific memory segment group
CDEFRAGMENTATION_DESC	Parameters for defragmentation
CDEFRAGMENTATION_MOVE	Single move of an allocation to be done for defragmentation
CDEFRAGMENTATION_PASS_MOVE_INFO	Parameters for incremental defragmentation steps
CDEFRAGMENTATION_STATS	Statistics returned for defragmentation process by function DefragmentationContext::GetStats()
CDefragmentationContext	Represents defragmentation process in progress
CDetailedStatistics	More detailed statistics than D3D12MA::Statistics
CPool	Custom memory pool
CPOOL_DESC	Parameters of created D3D12MA::Pool object. To be used with D3D12MA::Allocator::CreatePool
CStatistics	Calculated statistics of memory usage e.g. in a specific memory heap type, memory segment group, custom pool, or total
CTotalStatistics	General statistics from current state of the allocator - total memory usage across all memory heaps and segments
CVIRTUAL_ALLOCATION_DESC	Parameters of created virtual allocation to be passed to VirtualBlock::Allocate()
CVIRTUAL_ALLOCATION_INFO	Parameters of an existing virtual allocation, returned by VirtualBlock::GetAllocationInfo()
CVIRTUAL_BLOCK_DESC	Parameters of created D3D12MA::VirtualBlock object to be passed to CreateVirtualBlock()
CVirtualAllocation	Represents single memory allocation done inside VirtualBlock
CVirtualBlock	Represents pure allocation algorithm and a data structure with allocations in some memory block, without actually allocating any GPU memory
