Scala可以异步运行循环吗？

import scala.concurrent.{Future, Promise}
import scala.concurrent.ExecutionContext.Implicits.global

def asyncLoop(start: Int, end: Int): Future[Unit] = {
  if (start <= end) {
    // 执行当前循环迭代的操作
    val currentOperation = Future {
      // 这里是当前循环迭代的操作逻辑
      println(s"Current iteration: $start")
      // 模拟异步操作
      Thread.sleep(1000)
    }

    // 创建下一次循环迭代的Future，并在当前Future完成后触发执行
    val nextIteration = Promise[Unit]()
    currentOperation.onComplete(_ => nextIteration.success(()))
    nextIteration.future.flatMap(_ => asyncLoop(start + 1, end))
  } else {
    Future.successful(())
  }
}

// 调用异步循环函数
val result = asyncLoop(1, 5)
result.onComplete(_ => println("Async loop completed."))
