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: mod.rs
    path of file: ./repos/cargo-mobile/src/os/macos
    
    the code of the file until where you have to start completion: mod ffi;
pub(super) mod info;

use core_foundation::{
    array::CFArray,
    base::{OSStatus, TCFType},
    error::{CFError, CFErrorRef},
    string::{CFString, CFStringRef},
    url::CFURL,
};
use std::{
    ffi::OsStr,
    fmt::{self, Display},
    path::{Path, PathBuf},
    ptr,
};

// This can hopefully be relied upon... https://stackoverflow.com/q/8003919

#[derive(Debug)]

    LookupFailed(CFError),

        let path = path.as_ref();
        let item_url = CFURL::from_path(path, path.is_dir()).ok_or_else(|| {
            OpenFileError::PathToUrlFailed {
                path: path.to_owned(),
            }
        })?;
        let items = CFArray::from_CFTypes(&[item_url]);
        let spec = ffi::LSLaunchURLSpec::new(

        );
        let status = unsafe { ffi::LSOpenFromURLSpec(&spec, ptr::null_mut()) };
        if status == 0 {
