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/Deadliner/schedular/src
    
    the code of the file until where you have to start completion: mod macros;
mod notify;
mod server;
mod startup_launch;
mod system_tray;

use std::{
    env, fs,
    sync::{Arc, Mutex},
};

use chrono::{Local, NaiveDateTime};
use deadliner_gui::{generate_deadline_over_wallpaper, new_path, update_wallpaper, Sanit
    
fn get_minutes_left(conf: &SanitizedConf) -> i64 {
    let today = Local::now().naive_local();
    let deadline = NaiveDateTime::parse_from_str(&conf.deadline_str, "%Y-%m-%d %I:%M %p").unwrap();
    let diff = deadline.signed_duration_since(today);

    let minutes = diff.num_minutes();

    minutes
}
