}

Specific type of a binding.

For use in BindGroupLayoutEntry.

Corresponds to WebGPU’s mutually exclusive fields within GPUBindGroupLayoutEntry.

Variants

Buffer

A buffer binding.

Corresponds to WebGPU GPUBufferBindingLayout.

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<NonZero<u64>>

The minimum size for a BufferBinding matching this entry, in bytes.

If this is Some(size):

• When calling create_bind_group, the resource at this bind point must be a BindingResource::Buffer whose effective size is at least size.

• When calling create_render_pipeline or create_compute_pipeline, size must be at least the minimum buffer binding size for the shader module global at this bind point: large enough to hold the global’s value, along with one element of a trailing runtime-sized array, if present.

If this is None:

• Each draw or dispatch command checks that the buffer range at this bind point satisfies the minimum buffer binding size.

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

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.

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.

StorageTexture

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.

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.

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<(), Error>

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<GpuBindingType> for BindingType

fn from(binding_type: GpuBindingType) -> BindingType

Converts to this type from the input type.

impl Hash for BindingType

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 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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
