doc the change here - i don't understand it at all.

Code quote:

    let trait_id = item_id.trait_id(db);
    let trait_resolver_data = trait_id
        .resolver_data(db)
        .map_err(|_| SignatureError::FailedRetrievingSemanticData(item_id.full_path(db)))?;
    let trait_params_set: HashSet<_> = trait_resolver_data.generic_params.iter().collect();

    let function_generic_params: Vec<GenericParamId<'_>> = resolver_data
        .generic_params
        .iter()
        .filter(|param| !trait_params_set.contains(param))
        .cloned()
        .collect_vec();
