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/emacs-ng/rust_src
    
    the code of the file until where you have to start completion: // #[cfg(debug_assertions)]
use tracing_subscriber::{fmt, prelude::*, EnvFilter};

use emacs::bindings::{main1, terminate_due_to_signal, will_dump_p};

// Include the main c_exports file that holds the main rust_init_syms.
// This function calls the other crates init_syms functions which contain
// the generated bindings.
#[cfg(not(test))]
include!(concat!(env!("OUT_DIR"), "/c_exports.rs"));

#[no_mangle]
#[allow(unused_do
    
pub extern "C" fn main(argc: ::libc::c_int, argv: *mut *mut ::libc::c_char) -> ::libc::c_int {
    unsafe {
        if will_dump_p() {
            return main1(argc, argv);
        }
    }

    // install global collector configured based on EMACSNG_LOG env var.
    // #[cfg(debug_assertions)]
    tracing_subscriber::registry()
        .with(fmt::layer())
        .with(EnvFilter::from_env("EMACSNG_LOG"))
        .init();

    log::trace!("Emacs NG");

    unsafe { main1(argc, argv) };

    // emacs abort
    unsafe { terminate_due_to_signal(libc::SIGABRT, 40) };
    0
