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: erlang.rs
    path of file: ./repos/enigma/enigma/src/bif
    
    the code of the file until where you have to start completion: use crate::atom;
use crate::bif;
use crate::bitstring;
use crate::exception::{Exception, Reason};
use crate::process::RcProcess;
use crate::va
    
pub fn integer_to_binary_2(_vm: &Machine, process: &RcProcess, args: &[Term]) -> bif::Result {
    let radix = match args[1].into_variant() {
        Variant::Integer(i) if i >= 2 && i <= 16 => i as u8,
        _ => return Err(badarg!()),
    };

    match args[0].into_number() {
        Ok(value::Num::Integer(i)) => {
            let string = lexical::to_string_radix(i, radix).into_bytes();
            let heap = &process.context_mut().heap;

            Ok(Term::binary(heap, bitstring::Binary::from(string)))
        }
        Ok(value::Num::Bignum(i)) => {
            unimplemented!("integer_to_binary_2 with bignum");
            // let string = i.to_bytes_radix(radix);
            // let heap = &process.context_mut().heap;

            // Ok(Term::binary(
            //     heap,
            //     bitstring::Binary::from(string),
            // ))
        }
        _ => {
            println!("integer_to_list_2 called with {}", args[0]);
            Err(badarg!())
        }
    }
}
