What you did

Wrote a simple asset type without dependencies:

#[derive(Asset, TypePath)]
pub struct Rarity {
    pub name: SharedStr,
    pub color: Color,
}

What went wrong

Received an "unused variable" warning.

Additional information

cargo expand output:

pub struct Rarity {
    pub name: SharedStr,
    pub color: Color,
}
impl bevy::asset::Asset for Rarity {}

    fn visit_dependencies(
        &self,
        visit: &mut impl FnMut(bevy::asset::UntypedAssetId), // <-- Issue seems to be here
    ) {}
}
impl bevy::reflect::TypePath for Rarity {
