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: failed_cache.rs
    path of file: ./repos/CYFS/src/component/cyfs-stack/src/zone
    
    the code of the file until where you have to start completion: use cyfs_base::*;
use cyfs_core::*;

use lru_time_cache::{Entry, LruCache};
use std::sync::Arc;
use cyfs_debug::Mutex;

/*
用以缓存下面两种zone信息：
1. 对于device，无法读取其owner(owner没上链等情况)，签名无效等错误原因，导致无法得到正确的zone，只能使用单device的
    
    fn create_orphan_zone(device_id: &DeviceId) -> (ZoneId, Zone) {
        let owner = device_id.object_id().to_owned();
        let zone = Zone::create(
            owner,
            OODWorkMode::Standalone,
            vec![device_id.to_owned()],
            vec![],
        );
        let zone_id: ZoneId = zone.desc().calculate_id().try_into().unwrap();

        info!(
            "create new orphan zone for device={}, zone={}",
            device_id, zone_id
        );

        (zone_id, zone)
    }
