VkAndroidHardwareBufferUsageANDROID

To obtain optimal Android hardware buffer usage flags for specific image creation parameters, add a VkAndroidHardwareBufferUsageANDROID structure to the pNext chain of a VkImageFormatProperties2 structure passed to vkGetPhysicalDeviceImageFormatProperties2. This structure is defined as:

typedef struct VkAndroidHardwareBufferUsageANDROID {
    VkStructureType sType;
    void* pNext;
    uint64_t androidHardwareBufferUsage;
} VkAndroidHardwareBufferUsageANDROID;

pub struct AndroidHardwareBufferUsageANDROID {
    s_type: vk::StructureType,
    p_next: *mut c_void,
    android_hardware_buffer_usage: u64,
}

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• androidHardwareBufferUsage returns the Android hardware buffer usage flags.

The androidHardwareBufferUsage field must include Android hardware buffer usage flags listed in the AHardwareBuffer Usage Equivalence table when the corresponding Vulkan image usage or image creation flags are included in the usage or flags fields of VkPhysicalDeviceImageFormatInfo2. It must include at least one GPU usage flag (AHARDWAREBUFFER_USAGE_GPU_*), even if none of the corresponding Vulkan usages or flags are requested.
