Implementing Async Programming in Rust: Exploring async and await

Tutorial August 27, 2024
rust

Rust’s async ecosystem includes powerful libraries like tokio and async-std that provide runtime support for async operations. These libraries offer utilities for managing tasks, handling I/O, and more, making it easier to build concurrent applications.

#[tokio::main]
async fn main() {
    let urls = vec!["https://example.com", "https://rust-lang.org"];

    let futures = urls.into_iter().map(|url| fetch_data(url));
    let results: Vec<_> = futures::future::join_all(futures).await;

    for result in results {
        match result {
            Ok(data) => println!("Fetched data: {}", data),
            Err(e) => println!("Error fetching data: {}", e),
        }
    }
}
