Enum Device 

pub enum Device {
    Cpu,
    Wgpu(Arc<WgpuContext>),
}

Where a tensor lives and where its ops execute.

Variants

Cpu

Reference implementation used for testing and verification.

Wgpu(Arc<WgpuContext>)

Production backend: WebGPU via wgpu (Vulkan/Metal/D3D12/Browser).

Implementations

impl Device

pub fn wgpu() -> Result<Device>

Create the default WebGPU device (highest-performance adapter). Sync facade — native only; on wasm use Device::wgpu_async.

pub async fn wgpu_async() -> Result<Device>

Async device creation — the primary form (roadmap v4, pitfall 14); works on native and wasm32/browser.

pub fn describe(&self) -> String

Human-readable adapter description.

pub fn max_binding_bytes(&self) -> usize

Largest single buffer binding this device supports, in bytes. Large weights (GPT-2’s wte) are row-chunked to stay under this.

pub fn same_as(&self, other: &Device) -> bool

Two devices are compatible when tensors on them can be combined.

Trait Implementations

impl Clone for Device

fn clone(&self) -> Device

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Device

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
