Expand description

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<BufferSize>

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

If this is Some(size):

If this is None:

§

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.

§

AccelerationStructure

A ray-tracing acceleration structure binding.

Example WGSL syntax:

@group(0) @binding(0)
var as: acceleration_structure;

Example GLSL syntax:

layout(binding = 0)
uniform accelerationStructureEXT as;
