ObservableLike

@implicitNotFound("Cannot find implicit value for ObservableLike[${F}].\nBuilding this implicit value might depend on having an implicit\ns.c.ExecutionContext in scope, a Scheduler or some equivalent type.")
trait ObservableLike[F[_]] extends FunctionK[F, Observable]

A lawless type class that provides conversions to Observable.

Sample:

 // Conversion from cats.Eval
 import cats.Eval

 val source0 = Eval.always(1 + 1)
 val task0 = ObservableLike[Eval].apply(source0)

 // Conversion from Future
 import scala.concurrent.Future

 val source1 = Future.successful(1 + 1)
 val task1 = ObservableLike[Future].apply(source1)

 // Conversion from IO
 import cats.effect.IO

 val source2 = IO(1 + 1)
 val task2 = ObservableLike[IO].apply(source2)

Abstract methods

def apply[A](fa: F[A]): Observable[A]

Converts from F[A] to Observable[A], preserving referential transparency if F[_] is a pure data type and preserving interruptibility if the source is cancelable.
