VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE

The VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE structure is defined as:

typedef struct VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE {
    VkStructureType sType;
    void* pNext;
    uint32_t maxBufferDeviceAddressAllocationAlignment;
} VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE;

pub struct PhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    max_buffer_device_address_allocation_alignment: u32,
}

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• LIMITS MAXBUFFERDEVICEADDRESSALLOCATIONALIGNMENT
  maxBufferDeviceAddressAllocationAlignment indicates the maximum alignment which can be requested when allocating buffer device addresses.

If the implementation already requires device memory allocation alignments greater-or-equal to the minimum limit of 64 KiB, implementations should not advertise a larger limit than what the implementation already uses internally, effectively making this extension a no-op, while letting the application have some guarantees for returned device addresses.

If the VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
