How to Avoid Common Async Pitfalls in Rust

Avoid async pitfalls in Rust by ensuring all async functions are awaited, using .await on futures, and handling errors with Result types.

use trpl::Html;

async fn page_title(url: &str) -> Option<String> {
    let response_text = trpl::get(url).await.text().await;
    Html::parse(&response_text)
        .select_first("title")
        .map(|title| title.inner_html())
}

Always chain .await calls immediately after async operations to prevent blocking or dropping futures.

Async code in Rust lets you run tasks without waiting for them to finish, but you must explicitly tell the program when to wait using .await. If you forget to wait, your program might crash or skip steps. Think of it like ordering food: you place the order (start the task), but you must wait at the table (use .await) to actually receive it.
