public class VkPhysicalDeviceShaderFloat16Int8Features
extends org.lwjgl.system.Struct<VkPhysicalDeviceShaderFloat16Int8Features>
implements org.lwjgl.system.NativeResource

Structure describing features supported by VK_KHR_shader_float16_int8.

Description

If the VkPhysicalDeviceShaderFloat16Int8Features structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to GetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceShaderFloat16Int8Features can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_FLOAT16_INT8_FEATURES

Layout

 struct VkPhysicalDeviceShaderFloat16Int8Features {
     VkStructureType sType();
     void * pNext();
     VkBool32 shaderFloat16();
     VkBool32 shaderInt8();
 }

Constructor Details

VkPhysicalDeviceShaderFloat16Int8Features

public VkPhysicalDeviceShaderFloat16Int8Features(ByteBuffer container)

Creates a VkPhysicalDeviceShaderFloat16Int8Features instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

The created instance holds a strong reference to the container object.

Method Details

sizeof

public int sizeof()

Specified by:

sizeof in class org.lwjgl.system.Struct<VkPhysicalDeviceShaderFloat16Int8Features>

sType

public int sType()

a VkStructureType value identifying this structure.

pNext

public long pNext()

NULL or a pointer to a structure extending this structure.

shaderFloat16

public boolean shaderFloat16()

indicates whether 16-bit floats (halfs) are supported in shader code. This also indicates whether shader modules can declare the Float16 capability. However, this only enables a subset of the storage classes that SPIR-V allows for the Float16 SPIR-V capability: Declaring and using 16-bit floats in the Private, Workgroup (for non-Block variables), and Function storage classes is enabled, while declaring them in the interface storage classes (e.g., UniformConstant, Uniform, StorageBuffer, Input, Output, and PushConstant) is not enabled.

shaderInt8

public boolean shaderInt8()

indicates whether 8-bit integers (signed and unsigned) are supported in shader code. This also indicates whether shader modules can declare the Int8 capability. However, this only enables a subset of the storage classes that SPIR-V allows for the Int8 SPIR-V capability: Declaring and using 8-bit integers in the Private, Workgroup (for non-Block variables), and Function storage classes is enabled, while declaring them in the interface storage classes (e.g., UniformConstant, Uniform, StorageBuffer, Input, Output, and PushConstant) is not enabled.

sType

public VkPhysicalDeviceShaderFloat16Int8Features sType(int value)

Sets the specified value to the sType() field.

sType$Default

public VkPhysicalDeviceShaderFloat16Int8Features sType$Default()

Sets the STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_FLOAT16_INT8_FEATURES value to the sType() field.

Sets the specified value to the pNext() field.
