Function contract_native_tensor 

pub fn contract_native_tensor(
    lhs: &Tensor,
    axes_a: &[usize],
    rhs: &Tensor,
    axes_b: &[usize],
) -> Result<Tensor>

Contract two native tensors along matching axes.

Errors

Returns an error when the native contraction fails (a shape or index mismatch, or a backend failure).
