Rust Programming Tutorials, Guides & Best Practices

use std::future::Future;

fn my_future() -> impl Future<Output = i32> {
    async {
        // Simulate some asynchronous computation
        42
    }
}

async fn main() {
    let result = my_future().await;
    println!("The answer is {}", result);
}

• A Future represents a computation that will eventually produce a value.
• Rust’s Future is lazy, meaning it won’t do anything until it’s awaited.
