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: meta.rs
    path of file: ./repos/CYFS/src/service/ood-daemon/src/config_repo
    
    the code of the file until where you have to start completion: use super::DeviceConfigRepo;
use crate::config::*;
use cyfs_base::*;
use cyfs_core::*;
use cyfs_debug::Mutex;
use cyfs_meta_lib::{
    MetaClient, MetaClientHelper, MetaClientHelperWithObjectCache, MetaMinerTarget,
};
use cyfs_util::LOCAL_DEVICE_MANAGER;

use async_trait::async_trait;
use serde::{Deserialize, Serialize};
use std::str::FromStr;
use std::sync::Arc;

        self.service.retain(|item| {
