Implementations

impl NotificationManager

pub fn new(screen_width: usize, screen_height: usize) -> Self

Create a new notification manager positioned in the top-right corner.

pub fn notify( &mut self, summary: String, body: String, urgency: NotificationUrgency, app_name: String, ) -> u32

Post a new notification. Returns the assigned notification ID.

pub fn dismiss(&mut self, id: u32)

Dismiss a specific notification by ID.

pub fn dismiss_all(&mut self)

Dismiss all active notifications.

pub fn tick(&mut self, current_tick: u64)

Tick the notification manager: remove expired and dismissed entries.

pub fn visible_notifications(&self) -> Vec<&Notification>

Return references to the currently visible (non-dismissed, non-expired) notifications, up to max_visible.

pub fn active_count(&self) -> usize

Return total count of active (non-dismissed, non-expired) notifications.

pub fn render_to_buffer( &self, buffer: &mut [u32], buf_width: usize, buf_height: usize, current_tick: u64, )

Render all visible toast notifications into a u32 pixel buffer.

The buffer is buf_width * buf_height pixels in BGRA format (one u32 per pixel). Toasts are rendered from the top-right corner, stacking downward. Only pixels belonging to toast rectangles are written; the caller is responsible for compositing this buffer as an overlay.
