Concrete methods

@inline
def fold[R](z: R)(op: (R, T) => R): Observable[R]

we not named foldLeft to indicate that Observable may emit items "out of order" (not like Future) Ex: Observable.from(2, 1).flatMap(Observable.timer(_ seconds)).fold("")(_ + _) is Observable of "12" (not "21")

Note

result may "out of order"

@inline
def scConcatMap[R](f: T => Observable[R]): Observable[R]

scala concatMap. We can't name concatMap because scala compiler will not implicitly pick this method.

Note

If don't need in-order then you should use scFlatMap

def toFuture: Future[T]
Note

if underlying:

  • is empty then toFuture will fail with NoSuchElementException("Sequence contains no elements")
  • emit more than one values then toFuture will fail with IllegalArgumentException("Sequence contains too many elements")
