Not really a bug but more a question for help.

I am trying to put a song in the queue and then play it after 35 seconds skip it and repeat.
but I get errors I'm stuck on this for a few days now and it is really demotivating.
I hope I don't break any rules I just need a little help.

Reposetory
File in question

my code


fn print_type_of<T>(_: &T) {
    println!("{}", std::any::type_name::<T>())
}

let current_track = tracks.pop();
let track_id = current_track.as_ref().unwrap().track.as_ref().unwrap().id();

print_type_of(&current_track);
// Output: core::option::Option<rspotify_model::playlist::PlaylistItem>
print_type_of(&track_id);
// Output: &core::option::Option<&dyn rspotify_model::idtypes::PlayableId>
print_type_of(&client);
// Output: rspotify::auth_code::AuthCodeSpotify

// My problem
&client.add_item_to_queue(track_id.unwrap(), Some(device_id.unwrap().as_str()));

Errors I get

If I add a reference to track_id.unwrap() when I call add_items_to_queue i get another error that I edited into the OP but I will put it here too

code

let current_track = tracks.pop();
let track_id = current_track.unwrap().track.unwrap().id();
client.add_item_to_queue(&track_id.unwrap(), None);

I also updated the repo if that is any helpful to you with those 3 lines of code

Ah sorry, I removed my comment because I had misread it. It looks like the repository you shared is private and I can't see the files.

Also, it looks like you want to return a Result so that you can avoid so many unwraps with the ? operator instead.

This will probably become a bit easier to use after #305 is merged and released in the next version. Maybe you should try with that? I'll try to bump it soon.

Sorry I made it public now

And I tried lots of different things with the track_id but I don't understand what it is supposed to be I know it would be this but I don't know what it is

Maybe I have to put a hold on this project and revisit it when #305 is merged

Yeah I think that's not possible until #305, sorry for the inconveniences! &dyn Trait doesn't implement Trait, only dyn Trait does. However, the function asks for a &Trait, so it's impossible to have both.

We'll try to get it merged this/next week and I'll ping you to get some feedback.
