Trait TensorReadEinsumExt 

pub trait TensorReadEinsumExt {
    // Required methods
    fn einsum_read<B: TensorBackend>(
        &self,
        subscripts: &str,
        backend: &mut B,
    ) -> Result<Tensor>;
    fn einsum_read_subscripts<B: TensorBackend>(

    ) -> Result<Tensor>;
}

Backend-explicit einsum methods for TensorRead inputs.

Use this surface when an input is a borrowed tensor view rather than an owned compact Tensor. The _read suffix follows the repository-wide convention for APIs that explicitly accept read-oriented borrowed inputs.

Examples

use tenferro_cpu::CpuBackend;
use tenferro_einsum::TensorReadEinsumExt;
use tenferro_tensor::{Tensor, TensorRead, TensorView};

let shape = [2, 3];
let data = [1.0_f64; 6];
let rhs = Tensor::from_vec_col_major(vec![3], vec![1.0_f64; 3]).unwrap();
let inputs = [
    TensorRead::from_view(TensorView::f64(&shape, &data)?),
    TensorRead::from_tensor(&rhs),
];
let mut backend = CpuBackend::new();

let out = inputs.einsum_read("ij,j->i", &mut backend)?;
assert_eq!(out.shape(), &[2]);

Required Methods

fn einsum_read<B: TensorBackend>( &self, subscripts: &str, backend: &mut B, ) -> Result<Tensor>

Execute an einsum from string notation over read-only tensor inputs.

fn einsum_read_subscripts<B: TensorBackend>( &self, subscripts: &EinsumSubscripts, backend: &mut B, ) -> Result<Tensor>

Execute an einsum from parsed integer-label subscripts over read-only tensor inputs.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
