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: custom_attributes.rs
    path of file: ./repos/freya/crates/state/src
    
    the code of the file until where you have to start completion: use std::any::Any;
use std::fmt::Debug;
use std::fmt::Display;
use std::sync::Arc;
use std::sync::Mutex;

use accesskit::NodeId as AccessibilityId;
use bytes::Bytes;

use freya_common::{CursorLayoutResponse, NodeReferenceLayout};
use freya_engine::prelude::*;
use tokio::sync::mpsc::UnboundedSender;
use tokio::sync::watch;
use torin::geometry::{Area, CursorPoint};
use uuid::Uuid;

    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        match self {
