def run[U](effect: Option[A] => U): Cancelable

Evaluate this Rx[A] and apply the given effect function. Once OnError(e) or OnCompletion is observed, it will stop the evaluation.

def runContinuously[U](effect: Option[A] => U): Cancelable

Keep evaluating Rx[A] even if OnError(e) or OnCompletion is reported. This is useful for keep processing streams.

def tap(f: Option[A] => Unit): Rx[A]

Applies f to the value for having a side effect, and return the original value.

Applies f to the value for having a side effect, and return the original value.

The difference from tapOn is that this method will not receive an input failure.

Value parameters

f

side-effect function used when observing a value

Attributes

Returns

the original Rx event

Inherited from:
RxOps
def tapOn(f: PartialFunction[Try[Option[A]], Unit]): Rx[A]

Applies f to the value for having a side effect, and return the original value.

Applies f to the value for having a side effect, and return the original value.

This method is useful for debugging Rx chains. For example:

 rx.tapOn {
   case Success(v) => debug(s"received ${v}")
   case Failure(e) => error(s"request failed", e)
 }

Value parameters

f

partial function for the side effect

Attributes

Returns

the original Rx event

Inherited from:
RxOps
def tapOnFailure(f: Throwable => Unit): Rx[A]

Applies f to the error if it happens, and return the original value.

Applies f to the error if it happens, and return the original value.

This method is useful for logging the error.

Value parameters

f

side-effect function used when observing an error

Attributes

Returns

the original Rx event
