Örneğin, şöyle bir fonksiyonunuz varsa:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

programınız şu şekilde çalışabilir:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

        () -> {
          AbstractFuture<String> future = setFutureFuture.get();
          setFutureSetSuccess.set(currentFuture.get().setFuture(future));
          setFutureCompletionSuccess.set(future.set("hello-async-world"));
          awaitUnchecked(barrier);
        };
    Set<Object> finalResults = Collections.synchronizedSet(Sets.newIdentityHashSet());
    Runnable collectResultsRunnable =
        () -> {

Наприклад, якщо у вас є функція:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

ваша програма може виконуватись так:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function
