Trait Implementations

impl Clone for CanvasElement

fn clone(&self) -> CanvasElement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ElementExt for CanvasElement

fn changed(&self, other: &Rc<dyn ElementExt>) -> bool

fn diff(&self, other: &Rc<dyn ElementExt>) -> DiffModifies

fn layout(&self) -> Cow<'_, LayoutData>

fn effect(&self) -> Option<Cow<'_, EffectData>>

fn style(&self) -> Cow<'_, StyleState>

fn text_style(&self) -> Cow<'_, TextStyleData>

fn accessibility(&self) -> Cow<'_, AccessibilityData>

fn events_handlers( &self, ) -> Option<Cow<'_, FxHashMap<EventName, EventHandlerType>>>

fn clip(&self, context: ClipContext<'_>)

fn render(&self, context: RenderContext<'_>)

fn layer(&self) -> Layer

fn measure( &self, _context: LayoutContext<'_>, ) -> Option<(Size2D<f32, ()>, Rc<dyn Any>)>

fn should_hook_measurement(&self) -> bool

fn should_measure_inner_children(&self) -> bool

fn is_point_inside(&self, context: EventMeasurementContext<'_>) -> bool

impl PartialEq for CanvasElement

fn eq(&self, other: &CanvasElement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
