Struct NotificationCenter 

pub struct NotificationCenter { /* private fields */ }

The list of notifications a window has accumulated.

Implementations

impl NotificationCenter

pub fn new(ident: impl Into<Ident>, cx: &mut Context<'_, Self>) -> Self

pub fn capacity(self, capacity: usize) -> Self

How many records the centre holds before it drops the oldest. A capacity below one is raised to one.

pub fn show( &mut self, notification: Notification, cx: &mut Context<'_, Self>, ) -> bool

Files a notification and shows a toast of it, reporting whether the toast was delivered.

False means no ToastLayer is mounted, so nothing floated on screen — but the record is filed either way, which is exactly the point of the centre.

pub fn record(&mut self, notification: Notification, cx: &mut Context<'_, Self>)

Files a notification without showing a toast of it.

A repeat of an id already held replaces it, the way a repeated toast refreshes rather than stacking: one identity is one notification.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn holds(&self, id: &str) -> bool

Whether the centre still holds this notification.

pub fn is_read(&self, id: &str) -> Option<bool>

Whether one notification has been read, or None when it is not here.

pub fn unread(&self) -> UnreadCount

pub fn mark_read(&mut self, id: &str, cx: &mut Context<'_, Self>) -> bool

pub fn mark_all_read(&mut self, cx: &mut Context<'_, Self>)

pub fn dismiss(&mut self, id: &str, cx: &mut Context<'_, Self>) -> bool

Takes one notification out, reporting whether it was here.

pub fn clear(&mut self, cx: &mut Context<'_, Self>)

Takes every notification out.

Dismissing one and clearing them all are separate reports, because clearing is the gesture that loses reports nobody has read and a host may well want to ask about it.
