Enum ComputeBackend 

pub enum ComputeBackend {
    Cpu,
    Wgpu,
    Cuda {
        device_ordinal: usize,
    },
    Auto,
}

User-facing execution backend preference.

Variants

Cpu

Always execute on the host reference backend.

Wgpu

Use the portable WGPU path where supported by the operation.

Cuda

Use the native CUDA path on this device ordinal.

Fields

device_ordinal: usize

Auto

Select the best backend that initializes successfully.

Implementations

impl ComputeBackend

pub fn resolve(&self) -> Result<(Self, String), AcceleratorError>

Resolve Auto and report both the selected backend and why.

CUDA fallback is attempted only here, during initialization. Execution errors are intentionally never converted into a silent CPU fallback.
