How do I know duration of an AudioSource?

[glossy mango]

I want to limit quantity of audio sources by priority, and thus I need to track sounds with their duration.

With audio_assets: Res<Assets<Source>> and audio_assets.get(your_audio_source_handle).total_duration() I think? https://docs.rs/bevy/latest/bevy/audio/trait.Source.html#tymethod.total_duration

Source is a trait, not an asset

yeah, sorry ><"

Possible solution:

fn get_duration(source: AudioSource) ->      Option<Duration> {
    source.decoder().total_duration()
}

tested on wav audio files, it works.
seems to be inefficient solution for a runtime, better would be to get audio durations on loading assets, then save them somewhere in Resources
