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: lib.rs
    path of file: ./repos/tools/crates/rome_test_utils/src
    
    the code of the file until where you have to start completion: use json_comments::StripComments;
use rome_analyze::{AnalyzerAction, Analyzer
    
pub fn register_leak_checker() {
    // Import the atexit function from libc
    extern "C" {
        fn atexit(f: extern "C" fn()) -> c_int;
    }

    // Use an atomic Once to register the check_leaks function to be called
    // when the process exits
    static ONCE: Once = Once::new();
    ONCE.call_once(|| unsafe {
        countme::enable(true);
        atexit(check_leaks);
    });
}
