Struct MarkerContext 

#[non_exhaustive]
pub struct MarkerContext {
    pub position: Pos2,
    pub zoom: f32,
    pub kind: SteadyAnimation,
    pub node_id: usize,
}

The context passed to NodeTemplate::marker_ui.

#[non_exhaustive], like NotificationContext, 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.

kind: SteadyAnimation

Which persistent effect to draw. For a node’s own lasting state (set through Map::node’s halo/blink/orbit) this is whichever of those was requested; for a plain marker (registered with Map::update_marker) it is always MapSettings::marker_animation, since every marker shares that one setting. There is no way from inside this hook to tell the two cases apart – only which SteadyAnimation to draw for whichever one it is.

node_id: usize

The id of the node the state/marker belongs to (for a marker: the id it points at, not the marker’s own id).
