Using ArcSwap in an async environment

[radhard]

I'm trying to update a struct that is enclosed in an ArcSwap and Arc: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=9a80238ee30a62e57a3640619f4044d1

However, I am getting an error for the following function:

fn internal_bug_grower(bug: &mut Arc<ArcSwap<Bug>>) {
    let mut new_bug = bug.clone().load();
    new_bug.grow_bug();
    bug.store(Arc::new(new_bug)); // this fails
}

I have tried several ways of doing this such as removing the Arc (bug.store(new_bug)), dereferencing the guard (bug.store(*new_bug)), cloning etc, but I cannot get it to work.

Never mind, I solved it in the following way:

fn internal_bug_grower(bug: &mut Arc<ArcSwap<Bug>>) {
    let mut new_bug = bug.load().as_ref().clone();
    new_bug.grow_bug();
    bug.store(Arc::new(new_bug)); 
}
