Error

Error: "async fn was not .awaited" — What It Means means you called an async function but forgot to add .await to execute it, leaving a Future that does nothing until polled. Add .await to the function call inside an async context to run the operation.

use trpl;

#[trpl::main]
async fn main() {
    let result = page_title("https://example.com").await;
    println!("{result}");
}

async fn page_title(url: &str) -> String {
    let response = trpl::get(url).await;
    response.text().await
}

An async function is like a recipe that hasn't started cooking yet; it just sits there until you tell it to begin. The .await keyword is the command that tells the computer to actually run the task and wait for the result. Without it, your code creates a task but never executes it, so nothing happens.
