Module binding 

Shared bind-group vocabulary for material and compute — a material’s own bind group and a compute pass’s own bind group are described the same way, differing only in which shader stage(s) can see each entry (a material entry can be FRAGMENT/VERTEX/VERTEX_FRAGMENT; a compute entry is always exactly COMPUTE). Every constructor below takes visibility explicitly rather than guessing a default per module — build_material/ build_compute validate it’s appropriate for the pipeline kind they’re building, panicking with a clear message otherwise.

Also useful directly (not just via MaterialDescriptor/ComputeDescriptor) any time you’re building a bind group layout by hand — BindGroupLayoutBuilder catches a duplicate @binding(N) with a clear panic instead of a wgpu validation failure at draw time. Re-exported, along with buffers, from wgpu::prelude.

Structs

BindGroupLayout

A wgpu::BindGroupLayout, opaque — built only via BindGroupLayoutBuilder::build. There’s no way to reach the underlying wgpu::BindGroupLayout from outside this crate. Clone because MaterialDescriptor::extra_layouts takes ownership (e.g. a camera’s layout, wired into more than one material) — cheap, the same Arc-backed handle underneath.

BindGroupLayoutBuilder

Builds a wgpu::BindGroupLayout one BindingEntry at a time.

BindingEntry

One binding within a material’s or compute pass’s own bind group (see MaterialDescriptor::entries/ComputeDescriptor::entries).

Enums

BindingKind

What kind of resource a single BindingEntry binds, the wgpu binding parameters that go with it, and which shader stage(s) can see it. Construct via the texture_*/*_buffer/sampler/storage_texture associated functions rather than the variants directly — they fill in the usual defaults (filterable float textures, non-dynamic buffers) so only the cases that actually differ need spelling out.

StorageTextureAccess

Access mode for a storage texture binding — mirrors wgpu::StorageTextureAccess.

TextureSampleType

Specific type of a sample in a texture binding — mirrors wgpu::TextureSampleType.

TextureViewDimension

Dimensions of a texture view — mirrors wgpu::TextureViewDimension.

Traits

BindGroupTarget

Implemented by GPUMaterial and GPUCompute — anything with its own bind group layout and named entries that a GPUBindingInstance can bind concrete resources against.
