rustHow to use an async yield in Rust?

Async/await is a Rust language feature that allows you to write asynchronous code in a synchronous-like style. It is based on the Future trait, which represents a value that will be available at some point in the future.

async fn foo() {
    let future = async {
        // Do some work
    };
    let result = await!(future);
    // Do something with the result
}

The code above shows a basic example of using async/await. The async keyword is used to mark a function as asynchronous, and the await! macro is used to wait for a Future to resolve.

Code explanation

• async keyword: marks a function as asynchronous
• let future = async { ... }: creates a Future that will be resolved at some point in the future
• let result = await!(future): waits for the Future to resolve and stores the result in the result variable
