What is Rust's async programming model?

Can you explain Rust's async programming model?

Sure! Rust's async programming model allows you to write asynchronous code using the async and await keywords, enabling non-blocking operations.

How does it differ from traditional threading?

Unlike traditional threading, which uses multiple OS threads, Rust's async model uses a single thread to manage multiple tasks, improving efficiency.

What are some common use cases for async in Rust?

Common use cases include web servers, network applications, and any I/O-bound tasks where you want to handle many operations concurrently.

Can you give an example of async code in Rust?

Certainly! Here's a simple example:

use tokio;

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

async fn async_function() -> i32 {
    42
}
