# VkPhysicalDeviceIndexTypeUint8Features(3) Manual Page

## Name

VkPhysicalDeviceIndexTypeUint8Features - Structure describing whether uint8 index type can be used

Loading… please wait.

## C Specification

The `VkPhysicalDeviceIndexTypeUint8Features` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceIndexTypeUint8Features {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           indexTypeUint8;
    } VkPhysicalDeviceIndexTypeUint8Features;

    // Provided by VK_KHR_index_type_uint8
    // Equivalent to VkPhysicalDeviceIndexTypeUint8Features
    typedef VkPhysicalDeviceIndexTypeUint8Features VkPhysicalDeviceIndexTypeUint8FeaturesKHR;

    // Provided by VK_EXT_index_type_uint8
    // Equivalent to VkPhysicalDeviceIndexTypeUint8Features
    typedef VkPhysicalDeviceIndexTypeUint8Features VkPhysicalDeviceIndexTypeUint8FeaturesEXT;

## Members

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.

## Description

- `indexTypeUint8` indicates that VK_INDEX_TYPE_UINT8 can be used with vkCmdBindIndexBuffer2 and vkCmdBindIndexBuffer.

If the `VkPhysicalDeviceIndexTypeUint8Features` 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. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceIndexTypeUint8Features`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceIndexTypeUint8Features-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INDEX_TYPE_UINT8_FEATURES

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
