Enum Resource 

pub enum Resource {
    Buffer(Buffer),
    Texture(Texture),
    TextureView(TextureView),
    Sampler(Sampler),
    Array(ArrayHandle),
    BindGroup(BindGroup),
    Virtual,
}

A wgpu resource owned by the graph, or a virtual node standing in for one.

This is the stored form, and the way to name a resource whose kind is only known at runtime: it is the erased ResHandle’s kind. Variants are thin — each holds the wgpu handle itself — so callers can keep working with raw wgpu and use the graph purely for bookkeeping.

Variants

Buffer(Buffer)

A buffer (vertex, index, uniform or storage).

Texture(Texture)

A texture.

TextureView(TextureView)

A texture view, with the format it views its texture as.

Sampler(Sampler)

A sampler.

Array(ArrayHandle)

A flat array of fixed-size elements, held either in a storage buffer or in a texture.

The two are one kind rather than two because they are one thing to a caller: which of them an array lives in follows from the device, not from what the array holds. See ArrayHandle.

BindGroup(BindGroup)

A bind group.

Virtual

A virtual node: no wgpu handle, purely a graph citizen.

It carries no GPU resource of its own: it is what an id over Virtual resolves to, and it exists to group or stand in for other nodes. The edges leaving it express ownership or derivation rather than handle derivation, which makes it the natural aggregation root for a group of resources that live and die together (see Retention).

It is an ordinary node otherwise: it takes dependencies like any other, and replacing it swaps one virtual value for another — a node’s kind never changes — while marking the nodes built from it dirty.

Implementations

impl Resource

pub fn kind_name(&self) -> &'static str

The name of this resource’s kind.

The stored form erases the kind, so this is how a caller that only has a Resource — a graph-wide read, a debug dump — reports which of the stored kinds it is looking at. The name matches the ResourceKind type it stands for: "Buffer", "TextureView", "Virtual", and so on.
