Struct ContractionDescriptor 

pub struct ContractionDescriptor { /* private fields */ }

Implementations

impl ContractionDescriptor

pub fn create( context: &Context, a: &TensorDescriptor, modes_a: &[Mode], b: &TensorDescriptor, modes_b: &[Mode], c: &TensorDescriptor, modes_c: &[Mode], d: &TensorDescriptor, modes_d: &[Mode], compute: ComputeType, ) -> Result<Self>

pub unsafe fn from_raw( handle: cutensorMgContractionDescriptor_t, context: &Context, a_pointer_count: usize, b_pointer_count: usize, c_pointer_count: usize, d_pointer_count: usize, ) -> Result<Self>

Wraps an existing cuTENSORMg contraction descriptor.

Safety

handle must be a valid cuTENSORMg contraction descriptor associated with context. Pointer counts must match the tensors used to create the descriptor. The returned value takes ownership of handle and destroys it on drop.

pub fn workspace( &self, find: &ContractionFind, preference: WorkspacePreference, ) -> Result<Workspace>

pub const fn as_raw(&self) -> cutensorMgContractionDescriptor_t

pub fn into_raw(self) -> cutensorMgContractionDescriptor_t

Consumes this descriptor and returns the owned raw cuTENSORMg descriptor.

The caller becomes responsible for destroying the descriptor.

Trait Implementations

impl Debug for ContractionDescriptor

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

Formats the value using the given formatter.

impl Drop for ContractionDescriptor

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.
