Struct MapSettings 

pub struct MapSettings {
    pub max_zoom: f32,
    pub min_zoom: f32,
    pub line_visible_zoom: f32,
    pub label_visible_zoom: f32,
    pub node_text_visibility: VisibilitySetting,
    pub styles: Vec<MapStyle>,
}

Configuration of a Map widget.

MapSettings::default() provides sensible zoom limits plus a light and a dark theme; the widget picks the style to apply based on egui::Visuals::dark_mode, using styles[0] in light mode and styles[1] in dark mode.

Fields

max_zoom: f32

Maximum zoom factor.

min_zoom: f32

Minimum zoom factor.

line_visible_zoom: f32

Zoom threshold above which connection lines become visible.

label_visible_zoom: f32

Zoom threshold above which node names become visible when node_text_visibility is VisibilitySetting::Always.

node_text_visibility: VisibilitySetting

Controls when node names are displayed.

styles: Vec<MapStyle>

Per-theme styles; index 0 is used in light mode, index 1 in dark mode.

Implementations

impl MapSettings

pub fn new() -> Self

Creates settings with all zoom thresholds set to 0.0 and a single transparent style.

Prefer MapSettings::default() unless you really need to build the configuration from scratch.
