Expand description
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<NonZeroU64>
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
.
