Not all compilers like this. Nothing stops a static_cast<> from setting
|button.type| to 42. What do we return in that case?

Instead, it's common for us to output an error and choose a default value.

    NOTREACHED();
    return NotificationActionType::BUTTON;

It *should* never be reached. Where the switch() gives you compile time
guarantees, the NOTREACHED() does the same for runtime guarantees.

nit: consider having a const reference to the button as the first line in the
loop, allows you to remove all the "[i]"s.

const auto& button = buttons[i];
