toString specification

This is the engineering specification for the MotionObservable operator: toString.


toString emits a string representation of the upstream value.

Example usage:


upstream  |  downstream
20        |  "20"
40        |  "40"
80        |  "80"


Expose a toString operator API

Use _map to implement the operator.

class MotionObservable {
  public func toString() -> MotionObservable<String>
