InterruptHandler

Embeds an "interrupt handler" into a Promise.

This is a total handler such that it's defined on any Throwable. Use Promise.setInterruptHandler() if you need to leave an interrupt handler undefined for certain types of exceptions.

Example: (p and q are equivalent, but p allocates less):

import com.twitter.util.Promise

val p = new Promise[A] with Promise.InterruptHandler {
  def onInterrupt(t: Throwable): Unit = setException(t)
}

val q = new Promise[A]
q.setInterruptHandler { case t: Throwable => q.setException(t) }

Self Type: InterruptHandler with Promise[_]
Note: Later calls to setInterruptHandler on a promise mixing in this trait will replace the embedded handler.
