Struct zng :: update :: UpdateDeliveryList Copy item path

impl UpdateDeliveryList

pub fn new(subscribers: Box<dyn UpdateSubscribers>) -> UpdateDeliveryList

New list that only allows subscribers.

pub fn new_none() -> UpdateDeliveryList

New list that does not allow any entry.

pub fn new_any() -> UpdateDeliveryList

New list that allows all entries.

This is the default value.

pub fn insert_wgt(&mut self, wgt: &impl WidgetPathProvider)

Insert the wgt and ancestors up-to the inner most that is included in the subscribers.

pub fn insert_window(&mut self, id: WindowId)

Insert the window by itself, the window root widget will be targeted.

pub fn search_all(&mut self)

Register all subscribers for search and delivery.

pub fn search_widget(&mut self, widget_id: WidgetId)

Register the widget of unknown location for search before delivery routing starts.

pub fn has_pending_search(&mut self) -> bool

If the list has pending widgets that must be found before delivery can start.

pub fn fulfill_search<'a, 'b>( &'a mut self, windows: impl Iterator<Item = &'b WidgetInfoTree>, )

Search all pending widgets in all windows, all search items are cleared, even if not found.

pub fn enter_window(&self, window_id: WindowId) -> bool

Returns true if the window is on the list.

pub fn enter_widget(&self, widget_id: WidgetId) -> bool

Returns true if the widget is on the list.

pub fn windows(&self) -> &IdSet<WindowId>

Windows in the delivery list.

pub fn widgets(&self) -> &IdSet<WidgetId>

Found widgets in the delivery list, can be targets or ancestors of targets.

pub fn search_widgets(&mut self) -> &IdSet<WidgetId>

Widgets still pending search or not found.

pub fn search_root(&mut self) -> bool

If search for window a root is pending.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.
