trait FutureLift[F[_], Future[_]] extends ~>[[A]F[Future[A]], F]
A type class for conversions from scala.concurrent.Future or
other Future-like data type (e.g. Java's CompletableFuture).
N.B. to use its syntax, you can import monix.catnap.syntax:
import monix.catnap.syntax._ import scala.concurrent.Future // Used here only for Future.apply as the ExecutionContext import monix.execution.Scheduler.Implicits.global // Can use any data type implementing Async or Concurrent import cats.effect.IO val io = IO(Future(1 + 1)).futureLift
IO provides its own IO.fromFuture of course, however
FutureLift is generic and works with
CancelableFuture as well.
import monix.execution.{CancelableFuture, Scheduler, FutureUtils} import scala.concurrent.Promise import scala.concurrent.duration._ import scala.util.Try def delayed[A](event: => A)(implicit s: Scheduler): CancelableFuture[A] = { val p = Promise[A]() val c = s.scheduleOnce(1.second) { p.complete(Try(event)) } CancelableFuture(p.future, c) } // The result will be cancelable: val sum: IO[Int] = IO(delayed(1 + 1)).futureLift

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomictypes, as alternative tojava.util.concurrent.atomicmonix.catnap exposes pure abstractions built on top of the Cats-Effect type classes:
monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.
monix.reactive exposes the
Observablepattern:Observableimplementationsmonix.tail exposes Iterant for purely functional pull based streaming:
BatchandBatchCursor, the alternatives to Scala'sIterableandIteratorrespectively that we are using within Iterant's encodingYou can control evaluation with type you choose - be it Task, Coeval, cats.effect.IO or your own as long as you provide correct cats-effect or cats typeclass instance.
