rustHow to loop async in Rust

Looping asynchronously in Rust is possible using the async/await syntax. The following example code shows how to loop asynchronously over a vector of strings:

async fn loop_async() {
    let strings = vec!["foo", "bar", "baz"];
    for s in strings {
        println!("{}", s);
    }
}

Output example

foo
bar
baz

Code explanation

• async fn loop_async(): declares an asynchronous function
• let strings = vec!["foo", "bar", "baz"];: creates a vector of strings
• for s in strings: loops over the vector of strings
• println!("{}", s);: prints the current string
