Trait HostReference 

pub trait HostReference:

    + 'static {
    // Required method
    fn execute(&self, inputs: &[&Tensor]) -> Result<Vec<Tensor>, Error>;
}

Host/reference implementation for an extension family.

This capability is optional. Backend-only extension families can omit it and still implement ExtensionOp; runtimes that specifically delegate to host reference execution must report a typed capability-missing error when this hook is absent.

Examples

use tenferro_ops::ext_op::HostReference;
use tenferro_tensor::Tensor;

#[derive(Debug)]
struct IdentityHost;

impl HostReference for IdentityHost {
    fn execute(&self, inputs: &[&Tensor]) -> tenferro_tensor::Result<Vec<Tensor>> {
        Ok(vec![inputs[0].clone()])
    }
}

let input = Tensor::from_vec_col_major(vec![1], vec![3.0_f64]).unwrap();
let output = IdentityHost.execute(&[&input]).unwrap();
assert_eq!(output[0].as_slice::<f64>().unwrap(), &[3.0]);

Required Methods

fn execute(&self, inputs: &[&Tensor]) -> Result<Vec<Tensor>, Error>

Execute the extension op on host/reference tensors.
