Combine Rx stream and Future operators.
Combine Rx stream and Future operators.
This method is useful when you need to call RPC multiple times and chain the next operation after receiving the response.
Rx.intervalMillis(1000)
.andThen { i => callRpc(...) } // Returns Future
.map { (rpcReturnValue) => ... } // Use the Future response

Await the completion of the first Rx result. This method is available only in Scala JVM.
Await the completion of the first Rx result. This method is available only in Scala JVM.
Note: Generally speaking, blocking operations should be avoided in reactive programming. Use this method only for testing purpose. Both airframe-http and AirSpec supports evaluating Rx[X] result (async) in a non-blocking way.

Cache the last item, and emit the cached value if available.
Cache the last item, and emit the cached value if available.
The cached value will be preserved to the operator itself even after cancelling the subscription. Re-subscription of this operator will immediately return the cached value to the downstream operator.
This operator is useful if we need to involve time-consuming process, and want to reuse the last result: val v = Rx.intervalMillis(1000).map(i => (heavy process)).cache
v.map { x => ... }

Emit a new output if one of Rx[A] or Rx[B] is changed.
Emit a new output if one of Rx[A] or Rx[B] is changed.
This method is useful when you need to monitor multiple Rx objects.
Using joins will be more intuitive than nesting multiple Rx operators like Rx[A].map { x => ... Rx[B].map { ...} }.

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)
}
