You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/citybound/cb_simulation/src/land_use/buildings/architecture
    
    the code of the file until where you have to start completion: use kay::{ActorSystem, World, TypedID};
use compact::{CHashMap};
use descartes::{N, P2, V2, WithUniqueOrthogonal, LinePath, ClosedLinePath, PrimitiveArea, Area};
use cb_util::random::{Rng, seed};
use cb_util::config_manager::Name;
use 
    
pub fn footprint_area(lot: &Lot, building_style: BuildingStyle, extra_padding: N) -> Area {
    if let BuildingStyle::Field = building_style {
        lot.area.clone()
    } else {
        // TODO keep original building if lot changes
        let mut rng = seed(lot.original_lot_id);

        let (base_width, base_depth) = footprint_dimensions(building_style);

        let (main_footprint, _entrance_footprint) =
            generate_house_footprint(lot, base_width, base_depth, extra_padding, &mut rng);

        Area::new(vec![main_footprint.as_primitive_area()].into())
    }
}
