Struct NotificationContext 

#[non_exhaustive]
pub struct NotificationContext {
    pub position: Pos2,
    pub zoom: f32,
    pub initial_time: Instant,
    pub color: Color32,
    pub kind: NodeAnimation,
    pub node_id: usize,
}

The context passed to NodeTemplate::notification_ui.

#[non_exhaustive] so a future field can be added here without another breaking change to NodeTemplate.

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.

initial_time: Instant

When the notification started – usually fed into a progress computation like Instant::now().duration_since(initial_time).

color: Color32

The color requested for this notification (the node’s own color, or the current style’s alert_color if none was set).

kind: NodeAnimation

Which built-in event effect was requested (pulse, ripple, …). Match on this to dispatch to the corresponding Animation function instead of reimplementing the lookup yourself.

node_id: usize

The id of the node this notification belongs to.
