pub trait Summary {
    fn summarize(&self) -> String {
        String::from("(Read more...)")
    }
}

fn notify<T: Summary>(item: T) {
    println!("Breaking news! {}", item.summarize());
}

async fn fetch_and_process_data(url: &str) -> Result<usize, reqwest::Error> {
    let data = fetch_data(url).await?;
    Ok(data.len())
}

• Error handling in async functions works similarly to synchronous functions.
• The ? operator can be used to propagate errors within an async context.
