Async (cactoos 0.54.0 API)

java.lang.Object
- org.cactoos.func.Async<X,Y>

Type Parameters:

X - Type of input

Y - Type of output

All Implemented Interfaces:

Func<X,Future<Y>>, Proc<X>
```
public final class Async<X,Y>
extends Object
implements Func<X,Future<Y>>, Proc<X>
```
Func that runs in the background.
If you want your piece of code to be executed in the background, use Async as following:
```
 int length = new AsyncFunc(
   input -> input.length()
 ).apply("Hello, world!").get();
```
There is no thread-safety guarantee.
Since:

0.10
