seconds Using Futures For Non-blocking Computation Basic use of futures is easy with the factory method on Future, which executes a provided function asynchronously, handing you back a future result of that function without blocking the current thread. This trampoline execution context is a great piece of software: it makes sure the callbacks are run on the same thread than the future to avoid context switchings. it does not overflow with recursive callbacks. To show the benefit of the trampoline execution context, let's call this function that does not make any sense, but simply calls Future The execution context scheduler reuses some scala.concurrent.ExecutionContext to do work-stealing tree scheduling: implicit val executionContextScheduler = { val ctx = scala.concurrent.ExecutionContext.Implicits.global val config = new Scheduler.Config.FromExecutionContext(4, ctx) new Scheduler.ExecutionContext(config) } import scala.concurrent.duration._ val d: Duration = 10. seconds Using Futures For Non-blocking Computation Basic use of futures is easy with the factory method on Future, which executes a provided function asynchronously, handing you back a future result of that function without blocking the current thread.
