Struct OperationDescriptor 

pub struct OperationDescriptor<'h> { /* private fields */ }

An un-compiled operation descriptor. Users typically create these through constructors on Contraction, Reduction, ElementwiseBinary, ElementwiseTrinary, or Permutation.

Implementations

impl<'h> OperationDescriptor<'h>

pub fn as_raw(&self) -> cutensorOperationDescriptor_t

Raw cutensorOperationDescriptor_t. Use with care.

pub fn estimate_workspace( &self, pref: &PlanPreference<'h>, kind: WorkspaceKind, ) -> Result<u64>

Estimate the scratch workspace required by a plan built from this descriptor + pref.

pub fn estimate_runtime( &self, pref: &PlanPreference<'h>, algo: i32, ) -> Result<f32>

Estimated runtime in milliseconds for this op at the given algorithm (cutensorAlgo::DEFAULT for auto).

pub fn num_algos(&self) -> Result<i32>

Number of algorithms cuTENSOR has for this op shape.

pub unsafe fn get_attribute( &self, attr: i32, buf: *mut c_void, size_bytes: usize, ) -> Result<()>

Low-level attribute getter (for attributes not exposed as typed fns).

Safety

buf must be writable for size_bytes matching attr.

pub unsafe fn set_attribute( &self, attr: i32, buf: *const c_void, size_bytes: usize, ) -> Result<()>

Low-level attribute setter.

Safety

buf must point at a buffer of size_bytes matching attr.

Trait Implementations

impl<'h> Debug for OperationDescriptor<'h>

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

Formats the value using the given formatter.

impl Drop for OperationDescriptor<'_>

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.
