Struct DenseVectorDescriptor 

pub struct DenseVectorDescriptor<'a> { /* private fields */ }

Implementations

impl<'a> DenseVectorDescriptor<'a>

pub fn create<T: DataTypeLike>( ctx: &Context, size: usize, values: &'a mut DeviceMemory<T>, ) -> Result<Self>

Initializes a dense vector descriptor.

The descriptor borrows the device value buffer by pointer; the buffer must outlive descriptor use or be replaced with DenseVectorDescriptor::set_values.

Errors

Returns an error if size cannot be represented by cuSPARSE, if cuSPARSE cannot create the descriptor, or if it returns a null handle.

pub fn values(&self) -> Result<DevicePtr>

Returns the values pointer of this dense vector descriptor.

Errors

Returns an error if cuSPARSE cannot report the values pointer.

pub fn set_values<T: DataTypeLike>( &mut self, values: &'a mut DeviceMemory<T>, ) -> Result<()>

Sets the values pointer of this dense vector descriptor.

The pointed-to device buffer must remain valid while the descriptor uses it.

Errors

Returns an error if cuSPARSE rejects the values pointer.

pub fn info(&self) -> Result<DenseVectorInfo>

Returns the fields of this dense vector descriptor.

Errors

Returns an error if cuSPARSE cannot report the descriptor fields or if the reported size cannot be represented as usize.

pub fn as_raw(&self) -> cusparseDnVecDescr_t

pub fn as_raw_const(&self) -> cusparseConstDnVecDescr_t

pub fn cuda_context(&self) -> &Arc<CudaContext>

pub unsafe fn from_raw( handle: cusparseDnVecDescr_t, ctx: &Context, ) -> Result<Self>

Wraps an existing cuSPARSE dense-vector descriptor and takes ownership of it.

Safety

handle must be a valid cusparseDnVecDescr_t. Any device buffer referenced by the descriptor must remain valid for lifetime 'a. Ownership of handle is transferred to the returned descriptor, and the handle must not be destroyed elsewhere after calling this function.

pub fn into_raw(self) -> cusparseDnVecDescr_t

Consumes the descriptor and returns the raw cuSPARSE handle without destroying it.

The caller becomes responsible for eventually destroying the returned handle with cusparseDestroyDnVec.

Trait Implementations

impl<'a> Debug for DenseVectorDescriptor<'a>

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

Formats the value using the given formatter.

impl Drop for DenseVectorDescriptor<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
