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: mod.rs
    path of file: ./repos/krustlet/crates/kubelet/src/plugin_watcher
    
    the code of the file until where you have to start completion: //! The Kubelet plugin manager. Used to lookup which plugins are registered with this node.
use crate::fs_watch::FileSystemWatcher;
use crate::grpc_sock;
use crate::plugin_registration_api::v1::{
    registra
    
    async fn test_reregistration() {
        // This path doesn't matter here
        let registrar = PluginRegistry::new("/tmp/foo");
        let info = valid_info();

        // Insert a valid registration
        let discovered_path = PathBuf::from("/tmp/foo/bar.sock");
        registrar.register(&info, &discovered_path).await;

        assert!(
            registrar.validate(&info, &discovered_path).await.is_ok(),
            "Exact same plugin info shouldn't fail"
        );
    }
