Struct WgpuAccelerator 

pub struct WgpuAccelerator { /* private fields */ }

GPU-backed accelerator using wgpu (Vulkan / Metal / DX12 / WebGPU).

If no GPU is available the constructor fails; use AcceleratorBuilder which transparently falls back to CpuAccelerator.

All operations currently delegate to the CPU path while the wgpu compute pipeline is being set up. The struct is intentionally structured so that individual operations can be migrated to GPU shaders without changing the public interface.

Implementations

impl WgpuAccelerator

pub fn new() -> Result<Self>

Create a WgpuAccelerator with automatic device selection.

Errors

Returns GpuError::NoAdapter if no GPU is available.

pub fn gpu_device(&self) -> &Arc<GpuDevice>

Underlying GPU device.
