Description

RX operators to look more into adding in IOxHelpers:

  • buffer(..) -- mostly the time based one, which is sorta zip-over-time
  • takeUntil(..) -- waits on a value from another IOx to signal it should stop taking
  • range(start,end) -- like seq(start,1) + take(end - start)
  • forkJoin(..) -- like zip(..) but waits to emit only the last set of values
  • concat(..) -- combinator (like merge(..) or zip(..), but goes in order)... would need a different name!
  • pluck(..) -- like IOx's version of prop(..)
  • find(..) -- like filterIn(..) + take(1)
  • timeout(..)

Contributor guide

Research direction
Study the RxJS implementations of buffer, takeUntil, range, forkJoin, concat, pluck, find, and timeout, then implement them in IOxHelpers following the monio library patterns.
