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: build.rs
    path of file: ./repos/LibAFL/fuzzers/libfuzzer_libmozjpeg
    
    the code of the file until where you have to start completion: // build.rs

use std::env;

fn main() {
    let out_dir = env::var_os("OUT_DIR").unwrap();
    let out_dir = out_dir.to_
    
fn main() {
    let out_dir = env::var_os("OUT_DIR").unwrap();
    let out_dir = out_dir.to_string_lossy().to_string();

    println!("cargo:rerun-if-changed=harness.c");

    cc::Build::new()
        // Use sanitizer coverage to track the edges in the PUT
        // Take advantage of LTO (needs lld-link set in your cargo config)
        //.flag("-flto=thin")
        .file("./hook_allocs.c")
        .compile("hook_allocs");

    println!("cargo:rustc-link-search=native={}", &out_dir);

    println!("cargo:rerun-if-changed=build.rs");
}
