// Err returns the reason for terminating the backoff, or nil if it didn't terminate.
func (b *Backoff) Err() error {
	if b.ctx.Err() != nil {
		return b.ctx.Err()
	}
	if b.cfg.MaxRetries != 0 && b.numRetries >= b.cfg.MaxRetries {
		return fmt.Errorf("terminated after %d retries", b.numRetries)
	}
	return nil
}

// ErrCause is like Err() but returns the context cause if backoff is terminated because the
// context has been canceled.
