Rust Async Patterns

Master asynchronous programming in Rust using async/await syntax, tokio runtime, and the futures ecosystem for concurrent I/O operations.

Async/Await Basics

Basic async function:

async fn fetch_data() -> String {
    String::from("data")
}

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