VkPhysicalDeviceASTCDecodeFeaturesEXT

The VkPhysicalDeviceASTCDecodeFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceASTCDecodeFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 decodeModeSharedExponent;
} VkPhysicalDeviceASTCDecodeFeaturesEXT;

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• decodeModeSharedExponent indicates whether the implementation supports decoding ASTC compressed formats to VK_FORMAT_E5B9G9R9_UFLOAT_PACK32 internal precision.

If the VkPhysicalDeviceASTCDecodeFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceASTCDecodeFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
