Struct map_gui::tools::DrawRoadLabels

pub struct DrawRoadLabels {
    per_zoom: RefCell<[Option<Drawable>; 11]>,
    include_roads: Box<dyn Fn(&Road) -> bool>,
    fg_color: Color,
    outline_color: Color,
}

Labels roads when unzoomed. Label size and frequency depends on the zoom level.

By default, the text is white; it works well on dark backgrounds.

Fields

per_zoom: RefCell<[Option<Drawable>; 11]>

include_roads: Box<dyn Fn(&Road) -> bool>

fg_color: Color

outline_color: Color
