Enum GpuError 

pub enum GpuError {
    CudaUnavailable,
    KernelFailed(i32),
    InvalidInput(&'static str),
}

Errors that the GPU pipeline can surface.

The most common variant on developer machines without an NVIDIA toolkit is CudaUnavailable; the CLI translates this into exit code 2 so it can be distinguished from a hash-chain divergence.

Variants

CudaUnavailable

The crate was built without the cuda feature, so no kernels are present. The CPU reference path still runs.

KernelFailed(i32)

A kernel returned a non-zero error code. The contained value is the raw status from the FFI boundary.

InvalidInput(&'static str)

One of the pipeline inputs disagrees with the contract (bad dimensions, oversize buffer, null pointer at the FFI boundary).

Trait Implementations

impl Clone for GpuError

fn clone(&self) -> GpuError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GpuError

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

Formats the value using the given formatter.

impl PartialEq for GpuError

fn eq(&self, other: &GpuError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
