Implementations

impl ElementWithUtils

pub fn get_drawing_area( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, layout: &Torin<NodeId>, scale_factor: f32, node_style: &StyleState, transform_state: &TransformState, ) -> Rect<f32, ()>

Measure the area that this element once rendered will use. This takes into consideration things like borders and shadows.

pub fn get_drawing_area_if_viewports_allow( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, layout: &Torin<NodeId>, scale_factor: f32, node_style: &StyleState, node_viewports: &ViewportState, transform_state: &TransformState, ) -> Option<Rect<f32, ()>>

Just like Self::get_drawing_area but only if all the viewports allow the element to be visible.

pub fn needs_cached_drawing_area( &self, node_ref: &NodeRef<'_, CustomAttributeValues>, transform_state: &TransformState, style_state: &StyleState, ) -> bool

Check if this element needs its drawing area to be cached in case it needs to be invalidated in the next frame due to potential rotation or scale changes.

pub fn needs_explicit_render( &self, node_transform: &TransformState, node_style: &StyleState, ) -> bool

Some elements such as rect might always need to rerender as Skia doesnt work well with clipped canvases with applied blur.

Trait Implementations

impl ElementUtils for ElementWithUtils

fn clip( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, canvas: &Canvas, scale_factor: f32, )

fn is_point_inside_area( &self, point: &Point2D<f64, ()>, node_ref: &NodeRef<'_, CustomAttributeValues>, layout_node: &LayoutNode, scale_factor: f32, ) -> bool

fn render( self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, canvas: &Canvas, font_collection: &mut RCHandle<skia_textlayout_FontCollection>, font_manager: &RCHandle<SkFontMgr>, fallback_fonts: &[String], images_cache: &mut ImagesCache, scale_factor: f32, )

fn element_drawing_area( &self, layout_node: &LayoutNode, node_ref: &NodeRef<'_, CustomAttributeValues>, scale_factor: f32, node_style: &StyleState, ) -> Rect<f32, ()>

fn element_needs_cached_area( &self, node_ref: &NodeRef<'_, CustomAttributeValues>, style_state: &StyleState, ) -> bool

Check if this element requires any kind of special caching. Mainly used for text-like elements with shadows. See crate::render::CompositorCache. Default to false.
