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: tracker.rs
    path of file: ./repos/CYFS/src/component/cyfs-debug/src/check
    
    the code of the file until where you have to start completion: use std::fmt;
use std::sync::Mutex;
use std::time::Duration;

lazy_static::lazy_static! {
    static ref TIMER: Mutex<timer::Timer> = {
        warn!("tracker timer manager launched...");
        Mutex::new(timer::Timer::new())
    };
}

#[derive(Clone, Eq, PartialEq)]
pub enum TimeoutTrackerCategory {
    EnterLock,
    Lock,
    Scope,

    fn fmt(&self, fmt: &mut fmt::Formatter) -> fmt::Result {
        let v = match *self {
            TimeoutTrackerCategory::EnterLock => "enter_l
    
    pub fn new(categroy: TimeoutTrackerCategory, name: impl Into<String>, dur: Duration) -> Self {
        let categroy1 = categroy.clone();
        let name = name.into();
        let dur = chrono::Duration::from_std(dur).unwrap();
        let name1 = name.clone();
        let timer = TIMER
            .lock()
            .unwrap()
            .schedule_with_delay(dur.clone(), move || {
                error!(
                    "tracker during extend limit: categroy={}, name={}, dur={}",
                    categroy1, name1, dur
                );
            });

        Self {
