async fn getnum() -> i32 { println!("hello world"); sleep(Duration::frommillis(100)).await; 123 }

asyncstatic! { static ref FOO:i32 = getnum().await; }

/// run print /// /// hello world /// The result of the first call: 123 /// The result of the second call: 123 ///

[tokio::test]

async fn test() { // The first call, print hello world let n = FOO.await; println!("The result of the first call: {}", n);
