Function init 

pub fn init() -> Result<(), Error>

Initializes the job queue system by:

1. Setting up a logger via env_logger::init.
2. Attempting to acquire a database connection using DB::get_conn.
3. Running any pending database migrations using MIGRATIONS.
4. Starting the autoscaling worker system with start_autoscaling_worker.

Returns

• Ok(()) if all steps succeed.
• Err(diesel::result::Error) if a connection or migration step fails.

Examples

fn main() {
    // Initialize everything
    if let Err(e) = zirv_queue::init() {
        eprintln!("Failed to initialize queue system: {:?}", e);
        std::process::exit(1);
    }

    // The worker threads are now running in the background.
    // ...
}
