    typedef struct VkClusterAccelerationStructureCommandsInfoNV {
        VkStructureType                                           sType;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `input` is VkClusterAccelerationStructureInputInfoNV structure describing the build or move parameters for the cluster acceleration structure.

- `dstImplicitData` is the device address for memory where the implicit build of cluster acceleration structure will be saved. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV or VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, this value is ignored.

- `scratchData` is the device address of scratch memory that will be used during cluster acceleration structure move or build.

- `dstAddressesArray` is a VkStridedDeviceAddressRegionKHR that specifies addresses and stride for moved or built cluster acceleration structures, depending on the value of VkClusterAccelerationStructureInputInfoNV::`opMode`. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV and VkStridedDeviceAddressRegionKHR::`deviceAddress` is not `0`, then the implementation writes the cluster addresses to the specified region. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV, the implementation reads the cluster addresses from the specified region. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, this member is ignored.

- `dstSizesArray` is a VkStridedDeviceAddressRegionKHR containing sizes of moved or built cluster acceleration structures. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_IMPLICIT_DESTINATIONS_NV or VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_COMPUTE_SIZES_NV, then the sizes are saved. If VkClusterAccelerationStructureInputInfoNV::`opMode` is VK_CLUSTER_ACCELERATION_STRUCTURE_OP_MODE_EXPLICIT_DESTINATIONS_NV, then the sizes are read from.

- `srcInfosArray` is a VkStridedDeviceAddressRegionKHR where input data for the build or move operation is read from. If the stride is `0`, the structures are assumed to be packed tightly. Its format is dependent on VkClusterAccelerationStructureInputInfoNV::`opType` as per the table below.

`input.opType` | Format of `srcInfosArray`
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_MOVE_OBJECTS_NV | VkClusterAccelerationStructureMoveObjectsInfoNV
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_CLUSTERS_BOTTOM_LEVEL_NV | VkClusterAccelerationStructureBuildClustersBottomLevelInfoNV
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_NV | VkClusterAccelerationStructureBuildTriangleClusterInfoNV
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_BUILD_TRIANGLE_CLUSTER_TEMPLATE_NV | VkClusterAccelerationStructureBuildTriangleClusterTemplateInfoNV
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_INSTANTIATE_TRIANGLE_CLUSTER_NV | VkClusterAccelerationStructureInstantiateClusterInfoNV
VK_CLUSTER_ACCELERATION_STRUCTURE_OP_TYPE_GET_CLUSTER_TEMPLATE_INDICES_NV | VkClusterAccelerationStructureGetTemplateIndicesInfoNV

- `srcInfosCount` is the device address of memory containing the count of number of build or move operations to perform. The actual value is the minimum of this value and the value specified in `input.maxAccelerationStructureCount`. If this value is `0`, the count is determined by `input.maxAccelerationStructureCount` alone.

- `addressResolutionFlags` is a bitmask of VkClusterAccelerationStructureAddressResolutionFlagBitsNV values specifying how an implementation will interpret the device addresses in this structure.
