How do I handle timeouts with Scala Futures?

How do I handle timeouts with Scala Futures?

You can handle timeouts in Scala Futures using the Await.result method along with a specified timeout duration.

Can you show me an example of that?

Sure! Here's a simple example:

import scala.concurrent.{Await, Future}
import scala.concurrent.duration._
import scala.concurrent.ExecutionContext.Implicits.global

val future = Future {
  // Simulate a long-running task
  Thread.sleep(2000)
  "Result"
}

val result = Await.result(future, 1.second) // This will throw a TimeoutException

What happens if the future times out?

If the future times out, it will throw a TimeoutException, which you can catch and handle accordingly.

Is there a way to provide a fallback value?

Yes, you can use Future.firstCompletedOf to provide a fallback value if the original future fails or times out.
