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: device_state.rs
    path of file: ./repos/CYFS/src/component/cyfs-stack/src/sync/client
    
    the code of the file until where you have to start completion: use crate::root_state_api::GlobalStateLocalService;
use crate::zone::ZoneManagerRef;
use cyfs_base::*;
use cyfs_lib::*;

#[derive(RawEncode, RawDecode, Debug, Clone, Eq, PartialEq)]
pub struct LocalZoneState {
    // 当前zone的最新root state
    pub zone_root_s
    
    pub async fn load(&self) -> BuckyResult<()> {
        match self.state.load().await {
            Ok(_) => {
                info!(
                    "load device sync state success! state={:?}",
                    self.state.coll().lock().unwrap()
                );
                Ok(())
            }
            Err(e) => {
                error!(
                    "load device sync state failed! now will treat as init state: {:?}, err={}",
                    self.state.coll().lock().unwrap(),
                    e
                );
                Err(e)
            }
        }
    }
