Enum BlasError 

pub enum BlasError {
    Cuda(CudaError),
    InvalidDimension(String),
    BufferTooSmall {
        expected: usize,
        actual: usize,
    },
    DimensionMismatch(String),
    UnsupportedOperation(String),
    PtxGeneration(String),
    LaunchFailed(String),
    InvalidArgument(String),
    AutotuneError(String),
}

BLAS-specific error type.

Every fallible BLAS operation returns BlasResult<T> which uses this enum as its error variant. The variants are ordered roughly by how early in the call chain they are likely to appear: argument validation first, then PTX/launch errors, then driver-level failures.

Variants

Cuda(CudaError)

A CUDA driver call failed.

InvalidDimension(String)

A matrix or vector dimension is invalid (e.g. zero rows).

BufferTooSmall

A device buffer is too small for the requested operation.

Fields

expected: usize

Minimum number of elements required.

actual: usize

Actual number of elements in the buffer.

DimensionMismatch(String)

Two operands have incompatible dimensions (e.g. inner dims of A and B in a GEMM do not match).

UnsupportedOperation(String)

The requested operation or precision is not supported on this device.

PtxGeneration(String)

PTX kernel source generation failed.

LaunchFailed(String)

A kernel launch (grid/block configuration or driver call) failed.

InvalidArgument(String)

A caller-provided argument is invalid.

AutotuneError(String)

The autotuner encountered an error while profiling kernel variants.

Trait Implementations

impl Debug for BlasError

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

Formats the value using the given formatter.

impl Display for BlasError

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

Formats the value using the given formatter.

impl Error for BlasError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<CudaError> for BlasError

fn from(source: CudaError) -> Self

Converts to this type from the input type.

impl From<PtxGenError> for BlasError

fn from(err: PtxGenError) -> Self

Converts to this type from the input type.
