Enum rerun::external::eframe::egui_wgpu::wgpu::BindingResource

#[non_exhaustive]
pub enum BindingResource<'a> {
    Buffer(BufferBinding<'a>),
    BufferArray(&'a [BufferBinding<'a>]),
    Sampler(&'a Sampler),
    SamplerArray(&'a [&'a Sampler]),
    TextureView(&'a TextureView),
    TextureViewArray(&'a [&'a TextureView]),
    AccelerationStructure(&'a Tlas),
}

Resource that can be bound to a pipeline.

Corresponds to WebGPU GPUBindingResource.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Buffer(BufferBinding<'a>)

Binding is backed by a buffer.

Corresponds to wgt::BufferBindingType::Uniform and wgt::BufferBindingType::Storage with BindGroupLayoutEntry::count set to None.

BufferArray(&'a [BufferBinding<'a>])

Binding is backed by an array of buffers.

Features::BUFFER_BINDING_ARRAY must be supported to use this feature.

Corresponds to wgt::BufferBindingType::Uniform and wgt::BufferBindingType::Storage with BindGroupLayoutEntry::count set to Some.

Sampler(&'a Sampler)

Binding is a sampler.

Corresponds to wgt::BindingType::Sampler with BindGroupLayoutEntry::count set to None.

SamplerArray(&'a [&'a Sampler])

Binding is backed by an array of samplers.

Features::TEXTURE_BINDING_ARRAY must be supported to use this feature.

Corresponds to wgt::BindingType::Sampler with BindGroupLayoutEntry::count set to Some.

TextureView(&'a TextureView)

Binding is backed by a texture.

Corresponds to wgt::BindingType::Texture and wgt::BindingType::StorageTexture with BindGroupLayoutEntry::count set to None.

TextureViewArray(&'a [&'a TextureView])

Binding is backed by an array of textures.

Features::TEXTURE_BINDING_ARRAY must be supported to use this feature.

Corresponds to wgt::BindingType::Texture and wgt::BindingType::StorageTexture with BindGroupLayoutEntry::count set to Some.

AccelerationStructure(&'a Tlas)

Binding is backed by a top level acceleration structure

Corresponds to wgt::BindingType::AccelerationStructure with BindGroupLayoutEntry::count set to None.

Validation

When using (e.g. with set_bind_group) a bind group that has been created with one or more of this binding resource certain checks take place.

• TLAS must have been built, if not a validation error is generated
• All BLASes that were built into the TLAS must be built before the TLAS, if this was not satisfied and TLAS was built using build_acceleration_structures a validation error is generated otherwise this is a part of the safety section of build_acceleration_structures_unsafe_tlas and so undefined behavior occurs.
