Enum EinsumOperand 

pub enum EinsumOperand<'a> {
    F64(StridedData<'a, f64>),
    C64(StridedData<'a, Complex64>),
}

A type-erased einsum operand holding either f64 or Complex64 strided data.

Variants

F64(StridedData<'a, f64>)

C64(StridedData<'a, Complex64>)

Implementations

impl<'a> EinsumOperand<'a>

pub fn is_f64(&self) -> bool

Returns true if this operand holds f64 data.

pub fn is_c64(&self) -> bool

Returns true if this operand holds Complex64 data.

pub fn dims(&self) -> &[usize]

Return the dimensions of the underlying data.

pub fn permuted(self, perm: &[usize]) -> Result<Self>

Permute dimensions (metadata-only reorder, no data copy).

pub fn from_view<T: EinsumScalar>(view: &StridedView<'a, T>) -> Self

Create an EinsumOperand from a borrowed strided view.

Type inference selects the correct variant (F64 or C64) from the view’s element type.

pub fn to_c64_owned_ref(&self) -> EinsumOperand<'static>

Promote to an owned Complex64 operand by borrowing the data.

Unlike to_c64_owned, this works on &self and always copies.

pub fn to_c64_owned(self) -> EinsumOperand<'static>

Promote to an owned Complex64 operand.

• If already C64 and owned, returns as-is.
• If C64 view, copies into an owned array.
• If F64, converts each element to Complex64 and returns an owned array.
