Implementing Async Programming in Rust: Exploring async and await

Tutorial August 27, 2024
rust

A Future in Rust is an abstraction for a value that may not yet be available. Understanding how futures work is crucial to mastering async programming in Rust.

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);
}
