You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: binary.rs
    path of file: ./repos/tract/core/src/ops
    
    the code of the file until where you have to start completion: use crate::internal::*;
use downcast_rs::Downcast;
use std::fmt;
use tract_data::itertools::izip;

pub fn wire_cast(
    prefix: &str,
    target: &mut TypedModel,
    inputs: &[OutletId],
    operating_datum_type: DatumType,
) -> TractResult<TVec<OutletId>> {
    let mut wires = tvec!();
    for (ix, mut wire) in inputs.iter().copied().enumerate() {
        if target.outlet_fact(wire)?.datum_type != operating_da
    
    fn output_facts(&self, inputs: &[&TypedFact]) -> TractResult<TVec<TypedFact>> {
        if inputs[0].rank() != inputs[1].rank() {
            bail!("Typed ops require rank match. Invalid inputs for {}: {:?}", self.name(), inputs);
        }
        let out_dt = self.output_datum_type(inputs[0].datum_type, inputs[1].datum_type)?;
        Ok(tvec!(out_dt.fact(
            &*crate::broadcast::multi_broadcast(&[
                &inputs[0].shape.to_tvec(),
                &inputs[1].shape.to_tvec()
            ])
            .ok_or_else(|| format_err!(
                "Can not broadcast shapes a:{:?} b:{:?}",
                &inputs[0],
                &inputs[1]
            ))?
        )))
    }
