Struct SpGemmDescriptor 

pub struct SpGemmDescriptor { /* private fields */ }

Implementations

impl SpGemmDescriptor

pub fn create(ctx: &Context) -> Result<Self>

pub fn num_products(&self) -> Result<usize>

pub fn as_raw(&self) -> cusparseSpGEMMDescr_t

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

Wraps an existing cuSPARSE SpGEMM descriptor and takes ownership of it.

Safety

handle must be a valid cusparseSpGEMMDescr_t associated with ctx. 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) -> cusparseSpGEMMDescr_t

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

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

Trait Implementations

impl Debug for SpGemmDescriptor

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

Formats the value using the given formatter.

impl Drop for SpGemmDescriptor

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.
