[Question] Can I send an event to my statemachine from an action?

[joachimBurket]

Hi,

I'm trying to make a state machine that has a state which sends an Event from itself to the state machine. So this state is only doing an action, and then directly going to the next state.

Here is an example of what I would like to do:

enum Event {
    SongDownloaded,
}

struct MyStateMachine {
    player: MusicPlayer,
}

#[state_machine(
    initial = "State::idle()",
)]
impl MyStateMachine {
    pub fn new() -> Self {
        Self {
            player: MusicPlayer::new(),
        }
    }

    #[action]
    fn enter_download_song(&mut self) {
        // [ Do other actions here ]
        
        self.player.download_song();
        
        // TODO: Here I want to go to the next state when the song is downloaded.
        // self.handle(&Event::SongDownloaded);
    }
    #[state]
    fn download_song(event: &Event) -> Response<State> {
        match event {
            Event::SongDownloaded => Transition(State::playing())
            _ => Super,
        }
    }

   //  [ Other States ]
}

Is it possible to send an event from a state? Or maybe am I doing something not very conventional with the library / the states machine in general? 😅
