Introduction

Rust’s async/await syntax makes writing asynchronous code feel almost synchronous. Here’s a quick look at how it works.

Basic Example

use tokio::time::{sleep, Duration};

async fn fetch_data(id: u32) -> String {
    // Simulate network delay
    sleep(Duration::from_millis(100)).await;
    format!("Data for item {}", id)
}

#[tokio::main]
async fn main() {
    let result = fetch_data(42).await;
    println!("{}", result);
}

Spawning Concurrent Tasks

You can run multiple futures concurrently with tokio::join!:

async fn process_all() {
    let (a, b, c) = tokio::join!(
        fetch_data(1),
        fetch_data(2),
        fetch_data(3)
    );
    println!("Results: {}, {}, {}", a, b, c);
}
