public class VkPhysicalDeviceAccelerationStructurePropertiesKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Properties of the physical device for acceleration structure.
Description

Due to the fact that the geometry, instance, and primitive counts are specified at acceleration structure creation as 32-bit values, maxGeometryCount, maxInstanceCount, and maxPrimitiveCount must not exceed 2³²-1.

If the VkPhysicalDeviceAccelerationStructurePropertiesKHR structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to GetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Limits specified by this structure must match those specified with the same name in VkPhysicalDeviceRayTracingPropertiesNV.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_ACCELERATION_STRUCTURE_PROPERTIES_KHR
Layout
```
 struct VkPhysicalDeviceAccelerationStructurePropertiesKHR {
     VkStructureType sType();
     void * pNext();
     uint64_t maxGeometryCount();
     uint64_t maxInstanceCount();
     uint64_t maxPrimitiveCount();
     uint32_t maxPerStageDescriptorAccelerationStructures();

     uint32_t maxDescriptorSetAccelerationStructures();
