C ++ lade till stöd för async / await med version 20 2020 med 3 nya nyckelord co_return, co_await, co_yield Exempel C # An async/await will always return a Promise. Even if you omit the Promise keyword, the compiler will wrap the function in an immediately resolved Promise. This enables you to treat the return value of an async function as a Promise, which is quite useful when you need to resolve numerous asynchronous functions. As the name implies, async always Async database access with PostgreSQL, Play, Scala and Heroku Last year I felt I wanted to contribute in some way to the Scala community. Since I didn’t think I was smart enought to work on the main libraries or compiler, I started to look for something that I could build and would benefit me and the community in general.

It allows us to work with promises with less boilerplate. However, async/await do not replace the need for plain promises. For example, if we call an async function from a normal function or the global scope, we won’t be able to use await and will resort to vanilla promises: Use async/await as you used to know, inside actor ReceiveAsync.
As an alternative, Scala provides for-comprehensions to reduce the noise: Although useful, async/await is usually tied to a particular monad that represents
(this is a blocking action). the answer by Patryk is correct if a little difficult to follow. the main thing to understand about async/await is that it's just another way of doing Future's flatMap. there's no concurrency magic behind the scenes. 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.

Scala官方还提供了一个Async库，用来简化Scala异步操作，尽管这个库还没有正式加入到Scala的标准库中。 它是通过Scala macro 特性实现的。 async 用来标记一块异步执行的代码，通常这块代码中包含包含一个或者多个 await 调用。
