Struct NodeContext 

#[non_exhaustive]
pub struct NodeContext<'a> {
    pub position: Pos2,
    pub zoom: f32,
    pub point: &'a MapPoint,
    pub color: Color32,
}

The context passed to NodeTemplate::node_ui.

#[non_exhaustive], like NotificationContext/MarkerContext, so a future field can be added here without another breaking change.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

position: Pos2

The node’s screen position: already scaled by zoom and translated to the viewport origin.

zoom: f32

Multiply every size you draw by this so it scales with the map.

point: &'a MapPoint

The node being painted – its id, name, coordinates and connections.

color: Color32

The color requested for this node: point.color if the node has its own override, otherwise the active MapTheme’s ThemeColors::node for the current color mode – the same fallback the built-in circle uses when no template is installed, resolved once here so every NodeTemplate doesn’t need to repeat it.
