}

Specific type of a binding.

For use in BindGroupLayoutEntry.

Corresponds to WebGPU’s mutually exclusive fields within GPUBindGroupLayoutEntry.

Variants

Buffer

Fields

ty: BufferBindingType

Sub-type of the buffer binding.

has_dynamic_offset: bool

Indicates that the binding has a dynamic offset.

One offset must be passed to RenderPass::set_bind_group for each dynamic binding in increasing order of binding number.

min_binding_size: Option<BufferSize>

Minimum size of the corresponding BufferBinding required to match this entry. When pipeline is created, the size has to cover at least the corresponding structure in the shader plus one element of the unbound array, which can only be last in the structure. If None, the check is performed at draw call time instead of pipeline and bind group creation.

A buffer binding.

Corresponds to WebGPU GPUBufferBindingLayout.

Sampler(SamplerBindingType)

A sampler that can be used to sample a texture.

Example WGSL syntax:

@group(0) @binding(0)
var s: sampler;

Example GLSL syntax:

layout(binding = 0)
uniform sampler s;

Corresponds to WebGPU GPUSamplerBindingLayout.

Texture

Fields

sample_type: TextureSampleType

Sample type of the texture binding.

view_dimension: TextureViewDimension

Dimension of the texture view that is going to be sampled.

multisampled: bool

True if the texture has a sample count greater than 1. If this is true, the texture must be read from shaders with texture1DMS, texture2DMS, or texture3DMS, depending on dimension.

A texture binding.

Example WGSL syntax:

@group(0) @binding(0)
var t: texture_2d<f32>;

Example GLSL syntax:

layout(binding = 0)
uniform texture2D t;

Corresponds to WebGPU GPUTextureBindingLayout.

StorageTexture

Fields

access: StorageTextureAccess

Allowed access to this texture.

format: TextureFormat

Format of the texture.

view_dimension: TextureViewDimension

Dimension of the texture view that is going to be sampled.

A storage texture.

Example WGSL syntax:

@group(0) @binding(0)
var my_storage_image: texture_storage_2d<f32, write>;

Example GLSL syntax:

layout(set=0, binding=0, r32f) writeonly uniform image2D myStorageImage;

Note that the texture format must be specified in the shader as well. A list of valid formats can be found in the specification here: https://www.khronos.org/registry/OpenGL/specs/gl/GLSLangSpec.4.60.html#layout-qualifiers

Corresponds to WebGPU GPUStorageTextureBindingLayout.

Implementations

impl BindingType

pub fn has_dynamic_offset(&self) -> bool

Returns true for buffer bindings with dynamic offset enabled.

Trait Implementations

impl Clone for BindingType

fn clone(&self) -> BindingType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BindingType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BindingType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for BindingType

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

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<BindingType> for BindingType

fn eq(&self, other: &BindingType) -> 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 Serialize for BindingType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
