Struct Style 

pub struct Style {
    pub line_width: Option<f32>,
    pub font: Option<FontId>,
    pub background_color: Color32,
}

Visual style used to paint the map under a given theme.

Holds the non-palette visual configuration – stroke width, font, background – that combines with the active MapTheme’s ThemeColors when the widget paints. Style itself carries no color: every color the widget paints with (node fill, connection lines, alerts, selection, text) is resolved live from the installed MapTheme for the current ColorMode – see Map::set_theme – instead of living here as a copy that would need to be kept in sync.

Multiplying or dividing a Style by a number scales line_width and the font size; the widget uses this to scale the active style with the current zoom factor. Fields that are None are left untouched by those operators.

Fields

line_width: Option<f32>

Width of the connection lines between nodes; their color comes from the active MapTheme’s ThemeColors::segment. None disables the default stroke – a SegmentTemplate or a segment effect installed through Map::segment still runs either way.

font: Option<FontId>

Font used for map labels.

background_color: Color32

Background color of the map canvas.
