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: tuple.rs
    path of file: ./repos/rustler/rustler/src/wrapper
    
    the code of the file until where you have to start completion: use crate::wrapper::{c_int, NIF_ENV, NIF_ERROR, NIF_TERM};
use std::mem::MaybeUninit;

pub unsafe fn get_tuple<'a>(env: NIF_ENV, term: NIF_TERM) -> Result<&'a [NIF_TERM], NIF_ERROR> {
    let mut arity: c_int = 0;
    let mut array_ptr = MaybeUninit::uninit();
    let
    
pub unsafe fn get_tuple<'a>(env: NIF_ENV, term: NIF_TERM) -> Result<&'a [NIF_TERM], NIF_ERROR> {
    let mut arity: c_int = 0;
    let mut array_ptr = MaybeUninit::uninit();
    let success = rustler_sys::enif_get_tuple(env, term, &mut arity, array_ptr.as_mut_ptr());
    if success != 1 {
        return Err(NIF_ERROR::BAD_ARG);
    }
    let term_array = ::std::slice::from_raw_parts(array_ptr.assume_init(), arity as usize);
    Ok(term_array)
}
