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: sync_actor.rs
    path of file: ./repos/nearcore/chain/client/src/sync
    
    the code of the file until where you have to start completion: use super::adapter::{SyncMessage as ClientSyncMessage, SyncShardInfo};
use near_async::messaging::Sender;
use near_network::types::{PeerManagerMessageRequest, StateSyncResponse};
use near_o11y::{handler_debug_span, WithSpanContext};
use near_performance_metrics_macros::perf;
use near_primitives::hash::Cry
    
    fn handle_network_sync_message(&mut self, msg: StateSyncResponse) {
        match msg {
            StateSyncResponse::HeaderResponse => {
                debug!(target: "sync", shard_id = ?self.shard_uid.shard_id, "Got header response");
            }
            StateSyncResponse::PartResponse => {
                warn!(target: "sync", "Unsupported message received by SyncActor: SyncDone.");
            }
        }
    }
