Enum Tensor 

pub enum Tensor {
    F32(StructuredTensor<f32>),
    F64(StructuredTensor<f64>),
    C32(StructuredTensor<Complex<f32>>),
    C64(StructuredTensor<Complex<f64>>),
}

Runtime tensor wrapper for a fixed supported dtype set.

DynTensor is the canonical dynamic primal tensor type shared by tenferro frontends. Each variant carries a StructuredTensor<T>, so dense tensors and structured special cases such as Diag share the same container.

Examples

use tenferro_internal_frontend_core::{DynTensor, ScalarType, StructuredTensor};
use tenferro_tensor::{MemoryOrder, Tensor};

let t = Tensor::<f64>::from_slice(&[1.0, 2.0], &[2], MemoryOrder::ColumnMajor).unwrap();
let x: DynTensor = StructuredTensor::from(t).into();
assert_eq!(x.scalar_type(), ScalarType::F64);

Variants

F32(StructuredTensor<f32>)

F64(StructuredTensor<f64>)

C32(StructuredTensor<Complex<f32>>)

C64(StructuredTensor<Complex<f64>>)
