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: memory.rs
    path of file: ./repos/wasmtime/tests/all
    
    the code of the file until where you have to start completion: use rayon::prelude::*;
use std::sync::atomic::{AtomicU32, Ordering::SeqCst};
use std::time::{Duration, Instant};
use wasmtime::*;
use wasmtime_runtime::mpk;

fn module(engine: &Engine) -> Result<Module> {
    let mut wat = format!("(module\n");
    wat.push_str("(import \"\" \"\" (memory 0))\n");
    for i in 0..=33 {
        let offset = if i == 0 {
            0
        } else if i == 33 {
            !0
        } else {
            1u32 << (i - 1)

    
fn shared_memory_wait_notify() -> Result<()> {
    const THREADS: usize = 8;
    const COUNT: usize = 100_000;

    let engine = Engine::default();
    let memory = SharedMemory::new(&engine, MemoryType::shared(1, 1))?;
    let data = unsafe { &*(memory.data().as_ptr() as *const AtomicU32) };
    let locked = unsafe { &*(memory.data().as_ptr().add(4) as *const AtomicU32) };

    // Note that `SeqCst` is used here to not think much about the orderings
    // here, and it also somewhat more closely mirrors what's happening in wasm.
    let lock = || {
        while locked.swap(1, SeqCst) == 1 {
            memory.atomic_wait32(0, 1, None).unwrap();
        }
    };
    let unlock = || {
        locked.store(0, SeqCst);
        memory.atomic_notify(0, 1).unwrap();
    };

    std::thread::scope(|s| {
        for _ in 0..THREADS {
            s.spawn(|| {
                for _ in 0..COUNT {
                    lock();
                    let next = data.load(SeqCst) + 1;
                    data.store(next, SeqCst);
                    unlock();
                }
            });
        }
    });

    assert_eq!(data.load(SeqCst), (THREADS * COUNT) as u32);

    Ok(())
}
