rustHow to use async threads in Rust?

Async threads in Rust can be used to run multiple tasks concurrently. This can be done using the async and await keywords.

Example code

async fn hello_world() {
    println!("Hello, world!");
}

#[tokio::main]
async fn main() {
    hello_world().await;
}

Output example

Hello, world!

Code explanation

• async fn hello_world(): This declares an asynchronous function named hello_world.
• println!("Hello, world!");: This prints the string Hello, world! to the console.
• #[tokio::main]: This is an attribute that tells the compiler to use the Tokio runtime for the main function.
• hello_world().await;: This calls the hello_world function and waits for it to finish before continuing.
