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 namedhello_world
.println!("Hello, world!");
: This prints the stringHello, world!
to the console.#[tokio::main]
: This is an attribute that tells the compiler to use the Tokio runtime for themain
function.hello_world().await;
: This calls thehello_world
function and waits for it to finish before continuing.
