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: maps.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::exception::{Exception, Reason};
use crate::process::RcProcess;
use crate::value::{self, CastFrom, CastInto, Term, HAMT};
use crate::vm;

// TODO: deprecated past OTP 22
pub fn new_0(_vm: &vm::Machine,
    
    fn test_maps_take_2() {
        let vm = vm::Machine::new();
        let module: *const module::Module = std::ptr::null();
        let process = process::allocate(&vm, 0, 0, module).unwrap();
        let heap = &process.context_mut().heap;

        let map =
            map!(heap, str_to_atom!("test") => Term::int(1), str_to_atom!("test2") => Term::int(2));
        let key = str_to_atom!("test2");
        let args = vec![key, map];

        let res = take_2(&vm, &process, &args);
        if let Ok(tuple) = value::Tuple::cast_from(&res.unwrap()) {
            let mut iter = tuple.iter();
            assert_eq!(&Term::int(2), iter.next().unwrap());
            if let Ok(value::Map(map)) = iter.next().unwrap().cast_into() {
                assert_eq!(map.len(), 1);
                assert_eq!(map.get(&str_to_atom!("test")), Some(&Term::int(1)));
            } else {
                panic!();
            }
        } else {
            panic!();
        }
    }
