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: task_local.rs
    path of file: ./repos/async-std/tests
    
    the code of the file until where you have to start completion: use std::sync::atomic::{AtomicBool, Ordering};

use async_std::task;
use async_std::task_local;

#[cfg(not(target_os = "unknown"))]
use async_std::task::spawn;
#[cfg(target_os = "unknown")]
use async_std::task::spawn_local as spawn;

#[cfg(target_arch = "wasm32")]
wasm_bindgen_test::wasm_bindgen_test_configure!(run_in_browser);

#[test]
#[cfg_attr(target_arch = "wasm32", wasm_bindgen_test::wasm_bindgen_t
    
fn drop_local() {
    static DROP_LOCAL: AtomicBool = AtomicBool::new(false);

    struct Local;

    impl Drop for Local {
        fn drop(&mut self) {
            DROP_LOCAL.store(true, Ordering::SeqCst);
        }
    }

    task_local! {
        static LOCAL: Local = Local;
    }

    // Spawn a task that just touches its task-local.
    let handle = spawn(async {
        LOCAL.with(|_| ());
    });
    let task = handle.task().clone();

    // Wait for the task to finish and make sure its task-local has been dropped.
    task::block_on(async {
        handle.await;
        assert!(DROP_LOCAL.load(Ordering::SeqCst));
        drop(task);
    });
}
