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: version_checks.rs
    path of file: ./repos/lucet/lucet-runtime/tests
    
    the code of the file until where you have to start completion: use lucet_runtime::{DlModule, Error};
use lucetc::{Lucetc, LucetcOpts, VersionInfo};
use std::path::{Path, PathBuf};
use std::str
    
pub fn reject_old_modules() {
    // for platforms where modules are ELF (BSD, Linux, ...), exclude macos as it uses a different
    // file format (MachO)
    #[cfg(all(unix, not(target_os = "macos")))]
    const MODULE_PATH: &'static str = "./tests/version_checks/old_module.so";
    #[cfg(target_os = "macos")]
    const MODULE_PATH: &str = "./tests/version_checks/old_module.dylib";

    let err = DlModule::load(MODULE_PATH).err().unwrap();

    if let Error::ModuleError(e) = err {
        let msg = format!("{}", e);
        assert!(msg.contains("reserved bit is not set"));
        assert!(msg.contains("module is likely too old"));
    } else {
        panic!("unexpected error loading module: {}", err);
    }
}
