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: hooks.rs
    path of file: ./repos/Ambient/shared_crates/element/tests
    
    the code of the file until where you have to start completion: use std::sync::{
    atomic::{AtomicU32, Ordering},
    Arc,
};

use ambient_element::{
    use_effect, use_memo_with, use_state, Element, ElementComponent, ElementComponentExt,
    ElementTree, Hooks,
};
mod common;
use ambient_cb::cb;
use common::*;

#[test]
fn test_use_state() {
    #[derive(Debug, Clone, PartialEq, Eq)]
    pub struct Inner;
    impl ElementComponent for Inner {
        fn render(self: Box<Self>, hooks: &mut Hooks) -> Element {
            *hooks.world.resource_
    
fn test_use_state() {
    #[derive(Debug, Clone, PartialEq, Eq)]
    pub struct Inner;
    impl ElementComponent for Inner {
        fn render(self: Box<Self>, hooks: &mut Hooks) -> Element {
            *hooks.world.resource_mut(n_renders()) += 1;
            let (state, set_state) = use_state(hooks, 0);
            Element::new().on_spawned(move |_, _, _| set_state(state + 1))
        }
    }

    let mut world = initialize();
    let mut tree = Inner.el().spawn_tree(&mut world);
    assert_eq!(1, *world.resource(n_renders()));
    tree.update(&mut world);
    assert_eq!(2, *world.resource(n_renders()));
