Within an argument to a by-name parameter. Philipp was showing the async implementation of Scala.Collection.Immutable.RedBlackTree. C# Async, Await Examples This C# article uses the async and await keywords. It declares an async method and calls an async method with await.
Key points to keep in mind . Both async/await and the promise play the same role, but in the first case, use the `then` syntax, whereas in the second case use the async/await syntax. What is async? async marks a block of asynchronous code. Such a block usually contains one or more await calls, which marks a point at which the computation will be suspended until the awaited Future is complete.
(Only supported by CPS). Within local functions, local class, local objects. Within an argument to a by-name parameter.

(this is a blocking action). ‘Await’ must be called inside async. Withoutawait, the asynchronous function will end and it will not wait for the result of the asynchronous function. Key points to keep in mind .
See also scala/scala-async#73. A worthy optimization, suggested by @danarmak . Closes scala#73. async { await(slowCalcFuture) + await(slowCalcFuture) } We get to that block and hit the first await: async { await(slowCalcFuture) + await(slowCalcFuture) ^^^^^ } Ok, so we're asynchronously waiting for that calculation to finish. When it's finished, we 'move on' with analyzing the block:

2016-02-15 · scala.concurrent.Await object Await. Await is what is used to ensure proper handling of blocking for Awaitable instances.. While occasionally useful, e.g. for testing, it is recommended that you avoid Await when possible in favor of callbacks and combinators like onComplete and use in for comprehensions.
Such a block usually contains one or more await calls, which marks a point at which the computation will be suspended until the awaited Future is complete. By default, async blocks operate on scala.concurrent.{Future, Promise}. the answer by Patryk is correct if a little difficult to follow.

Use scala.concurrent.{Future, Promise}: def doAsyncAction: Promise[T] = { val p = Promise[T] p success doSomeOperation p } def useResult = { val async = doAsyncAction; // The return of the below is Unit. async.future onSuccess { // do action. }; }; Another way is to Await the result. (this is a blocking action).
