here is the function 

fn to_array32(s: &BigInt, size: usize) -> Vec<i32> {
    let mut res = vec![0; size as usize];
    let mut rem = s.clone();
    let radix = BigInt::from(0x100000000u64);
    let mut c = size - 1;
    while !rem.is_zero() {
        res[c] = (&rem % &radix).to_i32().unwrap();   // <-- error here
        rem /= &radix;
        c -= 1;
    }

    res
}
