Status is the cuSPARSE status code returned by cuSPARSE operations.

Variants

Success = 0

The operation completed successfully.

NotInitialized = 1

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 = 2

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

InvalidValue = 3

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

ArchMismatch = 4

The operation requires a feature absent from the device architecture.

MappingError = 5

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 = 6

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

InternalError = 7

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

MatrixTypeNotSupported = 8

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 = 9

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 = 10

The operation or data type combination is currently not supported.

InsufficientResources = 11

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.

Implementations

impl Status

pub const fn description(self) -> &'static str

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 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 From<Status> for cusparseStatus_t

fn from(value: Status) -> Self

Converts to this type from the input type.

impl From<Status> for u32

fn from(enum_value: Status) -> Self

Converts to this type from the input type.

impl From<cusparseStatus_t> for Status

fn from(value: 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,

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.

type Error = TryFromPrimitiveError<Status>

The type returned in the event of a conversion error.

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

Performs the conversion.

impl TryFromPrimitive for Status

const NAME: &'static str = "Status"

type Primitive = u32

type Error = TryFromPrimitiveError<Status>

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>
