Status is the cuSPARSE status code returned by cuSPARSE operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Success

The operation completed successfully.

NotInitialized

The cuSPARSE library was not initialized. Common causes include a missing Context::create call, a CUDA runtime error reported by cuSPARSE, or an error in the hardware setup. The error also applies when a matrix or vector descriptor is not initialized.

AllocFailed

Resource allocation failed inside the cuSPARSE library. Usually caused by a device memory allocation (cudaMalloc()) or host memory allocation failure.

InvalidValue

An unsupported value or parameter was passed to the operation, such as a negative vector size.

ArchitectureMismatch

The operation requires a feature absent from the device architecture.

MappingError

An access to GPU memory space failed, which is usually caused by a failure to bind a texture or an invalid device pointer. To correct: check that all device pointers are valid and that no texture is bound that could interfere with the operation.

ExecutionFailed

The GPU program failed to execute. A kernel launch failure on the GPU is a common cause.

InternalError

An internal cuSPARSE operation failed. Also check that memory passed to the operation is not released before the operation completes.

MatrixTypeNotSupported

The matrix type is not supported by this operation. Usually caused by passing an invalid matrix descriptor to the operation. Check that the fields in MatrixDescriptor were set correctly.

ZeroPivot

A zero pivot was encountered during the factorization. The operation cannot proceed because a diagonal element is zero. To correct: ensure the input matrix is non-singular.

NotSupported

The operation or data type combination is currently not supported.

InsufficientResources

The resources for the computation, such as GPU global or shared memory, are not sufficient to complete the operation. The error can also indicate that the current computation mode, such as sparse matrix index bit size, cannot handle the given input.

Unknown(u32)

A status code not known to this version of Singe.

Implementations

impl Status

pub fn description(self) -> String

pub const fn raw(self) -> u32

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Status

impl Debug for Status

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

Formats the value using the given formatter.

impl Display for Status

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

Formats the value using the given formatter.

impl Eq for Status

impl From<Status> for Error

fn from(code: Status) -> Self

Converts to this type from the input type.

impl From<cusparseStatus_t> for Status

fn from(status: cusparseStatus_t) -> Self

Converts to this type from the input type.

impl Hash for Status

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Status

fn eq(&self, other: &Status) -> 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.

impl StructuralPartialEq for Status

impl TryFrom<Status> for cusparseStatus_t

type Error = Status

The type returned in the event of a conversion error.

fn try_from(status: Status) -> Result<Self, Status>

Performs the conversion.

impl TryFrom<u32> for Status

type Error = u32

The type returned in the event of a conversion error.

fn try_from(code: u32) -> Result<Self, u32>

Performs the conversion.
