# VkPhysicalDeviceShaderExpectAssumeFeatures(3) Manual Page

## Name

VkPhysicalDeviceShaderExpectAssumeFeatures - Structure describing shader expect assume features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderExpectAssumeFeatures` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceShaderExpectAssumeFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderExpectAssume;
    } VkPhysicalDeviceShaderExpectAssumeFeatures;

or the equivalent

    // Provided by VK_KHR_shader_expect_assume
    typedef VkPhysicalDeviceShaderExpectAssumeFeatures VkPhysicalDeviceShaderExpectAssumeFeaturesKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `shaderExpectAssume` specifies whether shader modules can declare the `ExpectAssumeKHR` capability.

If the `VkPhysicalDeviceShaderExpectAssumeFeatures` 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 `VkPhysicalDeviceShaderExpectAssumeFeatures`, 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-VkPhysicalDeviceShaderExpectAssumeFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_EXPECT_ASSUME_FEATURES`
