Futures automatically capture exceptions raised in their bodies and reraise them when the future is derefed. Promises also throw exceptions when derefed.
Unlike promises, futures are created with the code that delivers their value, so calling fail and deliver explicitly on a future makes no sense. Think of futures as a thin wrapper around a promise which spawns a thread, runs the code, and to the wrapped promise either delivers the result of the code or calls (fail private-promise raised-exception) for you.
