Enum StateChange

pub enum StateChange {

    ExitNodes(Vec<(String, usize, TreeNode)>),
    WidgetConfig(Value),
}

Expand description

Changes to host-owned state that lives outside Core.

Variants§

§

SyncWindows

The window set may have changed; re-sync with renderer.

Produced after every Snapshot and Patch that succeeds. The host should compare tree.window_ids() against its open window set and open/close as needed.

§

ThemeChanged(Theme, ThemeChrome)

The global/root theme changed to an explicit value.

The host should update its cached theme and set theme_follows_system = false.

§

ThemeFollowsSystem

The root theme was set to "system": the app-level theme should follow the OS preference.

§

ExitNodes(Vec<(String, usize, TreeNode)>)

Nodes removed during a patch that had “exit” props. The host should promote these to ghost nodes for exit animations.

§

WidgetConfig(Value)

Widget configuration received from the host’s Settings message.

The host should call dispatcher.init_all(&config, &theme, ...) to pass configuration and context to registered widgets.

Source §

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

Source §

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.

Source §

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.

Source §

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.

Source §

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.

Source §

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

Source §

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.
