Enum SparseError 

pub enum SparseError {
    Cuda(CudaError),
    Blas(BlasError),
    PtxGeneration(String),
    InvalidFormat(String),
    DimensionMismatch(String),
    ZeroNnz,
    SingularMatrix,
    ConvergenceFailure(String),
    InternalError(String),
    InvalidArgument(String),
    Io(Error),
}

Sparse-specific error type.

Every fallible sparse operation returns SparseResult<T> which uses this enum as its error variant.

Variants

Cuda(CudaError)

A CUDA driver call failed.

Blas(BlasError)

A BLAS operation failed.

PtxGeneration(String)

PTX kernel generation failed.

InvalidFormat(String)

The sparse matrix format is invalid (e.g. mismatched array lengths).

DimensionMismatch(String)

Matrix dimensions are incompatible for the requested operation.

ZeroNnz

The number of non-zeros is zero, which is invalid for this operation.

SingularMatrix

The matrix is singular and cannot be factored or solved.

ConvergenceFailure(String)

An iterative algorithm failed to converge within the iteration limit.

InternalError(String)

An internal logic error (should not happen in correct code).

InvalidArgument(String)

A function argument is invalid.

Io(Error)

An I/O operation failed (e.g. PTX cache).

Trait Implementations

impl Debug for SparseError

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

Formats the value using the given formatter.

impl Display for SparseError

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

Formats the value using the given formatter.

impl Error for SparseError

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.
