Cloning a database object and using the cloned object and the original object.

[AlphabetsAlphabets]

Hi, I have a question about the following scenario.

1. I create a database object called db like this

    pub async fn new() -> Result<Self, SqlxError> {
        let db_path = "sqlite://database.db";
        let conn = SqlitePoolOptions::new().connect(db_path).await?;
        return Ok(Self { conn });
    }

2. I clone db and pass it in as an argument for an async task.

tokio::spawn(routine(db.clone())

This is the implementation of routine.

   async fn routine(db: Database) {
    loop {
        sleep(Duration::from_secs(60 * 5)).await;
        let _ = db.disqualify().await;
    }
}

I'm curoius about how the database operations are handled. disqualify requires write access and let's say 5 minutes are up and db.disqualify() runs and does its thing. Then at the same time I run another function that requires write access to the database as well. I'd like to know about the behaviour.

1. Will both functions return with an error, or
2. will it wait for one to finish executing before running the other function?

I'd prefer it to be option 2 since this code is used by multiple people at the same time, I'd prefer it if nothing crashes and service is cut off from all users.

Aside from these two questions I did find #917 (comment) where it is said that it's meant to be used this way, but I'd simply like some confirmation as to whether it still applies based on how I create the connection.

Thanks in advanced
