Trait Implementations§

Source§

impl State<App> for SelectBoundary

Source§

fn event(&mut self, ctx: &mut EventCtx<'_>, app: &mut App) -> Transition

Respond to a UI event, such as input or time passing.
Source§

fn draw(&self, g: &mut GfxCtx<'_>, app: &App)

Draw
§

fn draw_baselayer(&self) -> DrawBaselayer

Specifies what to draw before draw()
§

fn on_destroy(&mut self, _: &mut EventCtx<'_>, _: &mut A)

Before this state is popped or replaced, call this.
§

fn recreate(&mut self, _: &mut EventCtx<'_>, _: &mut A) -> Box<dyn State<A>>

Respond to Transition::Recreate by assuming state in the app has changed, but preserving the State-specific state appropriately.

Auto Trait Implementations§

Blanket Implementations§

Source§

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

Source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
Source§

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

Source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
Source§

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

Source§

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more
§

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.
