Enum ArrayHandle 

pub enum ArrayHandle {
    Buffer(Buffer),
    Texel(TextureView),
}

A flat array of fixed-size elements, as a bindable resource.

A device with storage buffers holds an array in one; a device without them — WebGL2 — holds the same bytes in a TexelArray the shader reads with textureLoad. A caller that has to work on both builds its bind group from this handle rather than from a buffer, so the two paths differ in how the array is uploaded and in nothing else.

See the module docs for how the texel path lays the bytes out.

Variants

Buffer(Buffer)

A storage buffer holding the whole array.

Texel(TextureView)

A texture holding the whole array.

Implementations

impl ArrayHandle

pub fn binding_resource(&self) -> BindingResource<'_>

The bind-group resource that binds this array.

pub fn layout_entry( &self, binding: u32, visibility: ShaderStages, element_size: u64, ) -> BindGroupLayoutEntry

The layout entry binding an array of element_size-byte elements held this way.

This is the Rust half of the shader’s interface: the composed variant declares a storage buffer on the buffer path and a non-filterable float texture on the texel path, and the two have to agree.
