For sbt projects add the following to your build definition - build.sbt or project/Build.scala: Use a modern Scala compiler In this video you will learn what async and await can be used for in coroutines.Get 60% on my Udemy course with the code ANDROID_DEVS:https://www.udemy.com/c 1 dag sedan · You haven't understood how async and await work. The result of an async function is a Promise, which will be resolved at some later time with the actual return value. Inside another async function, you can await that Promise to get the return value: If an async method doesn't use an Await operator to mark a suspension point, the method executes as a synchronous method does, despite the Async modifier. The compiler issues a warning for such methods. Async and Await are contextual keywords.

all the calls inside an async block are sequential, including await which doesn't actually block the executing thread but rather wraps the rest of the async block in a closure and passes it as a callback on completion of the Future we're waiting on. so in the first piece of code Se hela listan på github.com In the experimental Scala-async extension to Scala, await is a "method", although it does not operate like an ordinary method. Furthermore, unlike in C# 5.0 in which a method must be marked as async, in Scala-async, a block of code is surrounded by an async "call". How it works * This function denotes that we have asynchronous code we want to run via the "async" keyword * the "async" keyword tells the compiler to look for any "await" areas and make them non-blocking * in our example, we wish to fetch the contents of 2 files via http in a non-blocking manner * * @return a string wrapped in a Future result */ Se hela listan på alexn.org What is async?
