Race two computations

import ox.raceSuccess

def computation1: Int =
  Thread.sleep(2000)
  1

def computation2: Int =
  Thread.sleep(1000)
  2

val result: Int = raceSuccess(computation1)(computation2)
// 2

The losing computation is interrupted using Thread.interrupt. raceSuccess waits until both branches finish; this also applies to the losing one, which might take a while to clean up after interruption.

Error handling

• raceSuccess returns the first result, or re-throws the last exception

• raceResult returns the first result, or re-throws the first exception
