# VkPhysicalDeviceIndexTypeUint8FeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceIndexTypeUint8FeaturesEXT - Structure describing whether uint8 index type can be used

## C Specification

The `VkPhysicalDeviceIndexTypeUint8FeaturesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceIndexTypeUint8FeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           indexTypeUint8;
    } VkPhysicalDeviceIndexTypeUint8FeaturesEXT;

## Members

The members of the `VkPhysicalDeviceIndexTypeUint8FeaturesEXT` structure describe the following features:

## Description

- `indexTypeUint8` indicates that `VK_INDEX_TYPE_UINT8_EXT` can be used with vkCmdBindIndexBuffer.

If the `VkPhysicalDeviceIndexTypeUint8FeaturesEXT` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceIndexTypeUint8FeaturesEXT` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INDEX_TYPE_UINT8_FEATURES_EXT`
