A SPIR-V variable - interface variables, descriptor resources and push constants.

Variants

Input

Input interface variable.

Fields

name: Option<String>

location: InterfaceLocation

ty: Type

The concrete SPIR-V type definition of descriptor resource.

Output

Output interface variable.

Fields

name: Option<String>

location: InterfaceLocation

ty: Type

The concrete SPIR-V type definition of descriptor resource.

Descriptor

Descriptor resource.

Fields

name: Option<String>

desc_bind: DescriptorBinding

desc_ty: DescriptorType

Descriptor resource type matching VkDescriptorType.

ty: Type

The concrete SPIR-V type definition of descriptor resource.

nbind: u32

Number of bindings at the binding point. All descriptors can have multiple binding points. If the multi-binding is dynamic, 0 will be returned.

For more information about dynamic multi-binding, please refer to Vulkan extension VK_EXT_descriptor_indexing, GLSL extension GL_EXT_nonuniform_qualifier and SPIR-V extension SPV_EXT_descriptor_indexing. Dynamic multi-binding is only supported in Vulkan 1.2.

PushConstant

Push constant.

Fields

name: Option<String>

ty: Type

The concrete SPIR-V type definition of descriptor resource.

SpecConstant

Specialization constant.

Fields

name: Option<String>

spec_id: u32

Specialization constant ID.

ty: Type

The concrete SPIR-V type definition of descriptor resource.

Implementations

impl Variable

pub fn name(&self) -> Option<&str>

pub fn ty(&self) -> &Type

pub fn walk<'a>(&'a self) -> Walk<'a>

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Variable

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Variable

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Variable

fn eq(&self, other: &Variable) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Variable

impl StructuralPartialEq for Variable
