What is async programming in Rust?

What is async programming in Rust?

Async programming in Rust allows you to write non-blocking code, enabling efficient handling of concurrent tasks.

How does it differ from synchronous programming?

In synchronous programming, tasks are executed one after another, while async programming allows tasks to run concurrently, improving performance.

Can you give me an example of async code in Rust?

Sure! Here's a simple example using the tokio runtime:

use tokio::time;

#[tokio::main]
async fn main() {
    time::sleep(time::Duration::from_secs(1)).await;
    println!("Hello from async Rust!");
}

What libraries should I use for async programming in Rust?

Popular libraries include tokio, async-std, and futures. They provide tools for building async applications.
