Struct ModifierNodeSlices 

pub struct ModifierNodeSlices { /* private fields */ }

Re-export the UI crate so applications can depend on a single crate. Snapshot of modifier node slices that impact draw and pointer subsystems.

Implementations

impl ModifierNodeSlices

pub fn draw_commands(&self) -> &[DrawCommand]

pub fn outer_draw_command_count(&self) -> usize

How many leading draw_commands come from modifiers chained before the node’s graphics layer or clip. Those draw around the layer in the parent’s space, outside its clip, alpha and transform, exactly as an outer drawBehind wraps a graphicsLayer.

pub fn pointer_inputs(&self) -> &[Rc<dyn Fn(PointerEvent)>]

pub fn dispatch_pointer_event(&self, event: PointerEvent)

Dispatches an event whose position is already local to this layout node. Consumed events stop propagation except for release and cancellation, which reach every handler so each can finish its active interaction.

pub fn pointer_input_size_sinks(&self) -> &[Rc<Cell<Size>>]

The write targets for this node’s resolved size, one per pointer-input node that exposes a size to its handler. See ModifierNodeSlices::publish_pointer_input_size.

pub fn publish_pointer_input_size(&self, size: Size)

Publishes this layout node’s resolved size to every pointer-input handler attached to it, so PointerInputScope::size() reports the node’s real dimensions.

Called by every pass that resolves a node’s geometry (the layout place passes and the per-frame scene build), so the size is current before any pointer event for that frame is dispatched and tracks resizes.

size is the node’s layout box — the same box the dispatched PointerEvent positions are made local to — so handlers can compare event coordinates against it directly.

pub fn click_handlers(&self) -> &[Rc<dyn Fn(Point)>]

pub fn pointer_icon(&self) -> Option<&PointerIcon>

The pointer’s appearance over this node, when a pointer_icon modifier names one. The innermost declaration in the chain wins.

pub fn clip_to_bounds(&self) -> bool

pub fn motion_context_animated(&self) -> bool

pub fn translated_content_context(&self) -> bool

pub fn translated_content_context_identity(&self) -> Option<usize>

pub fn translated_content_offset(&self) -> Option<Point>

pub fn text_content(&self) -> Option<&str>

pub fn annotated_text(&self) -> Option<&AnnotatedString>

pub fn annotated_string(&self) -> Option<AnnotatedString>

pub fn text_style(&self) -> Option<&TextStyle>

pub fn text_layout_options(&self) -> Option<TextLayoutOptions>

pub fn text_pan_resolver(&self) -> Option<Rc<dyn Fn(f32) -> f32>>

Returns the horizontal pan resolver for single-line text fields.

The resolver takes the content viewport width (px) and returns the horizontal scroll offset that keeps the cursor visible. Renderers subtract this offset from the text origin so the glyphs pan together with the cursor and selection.

pub fn text_field_window_origin(&self) -> Option<Rc<Cell<Point>>>

The write target for a text field’s composited window origin, if this node is a BasicTextField. The layout pass writes the field’s true on-screen top-left here so its finger selection handles track the field across scroll. See ModifierNodeSlices::text_field_window_origin.

pub fn viewport_window_rect(&self) -> Option<Rc<dyn WindowRectSink>>

The write target for a scroll container’s composited window rect, if this node carries a report_window_rect modifier. The layout pass writes the node’s true on-screen viewport rect here so a BringIntoViewResponder can scroll a focused field’s caret above the soft keyboard.

pub fn prepare_text_layout( &self, max_width: Option<f32>, ) -> Option<PreparedTextLayout>

pub fn graphics_layer(&self) -> Option<GraphicsLayer>

pub fn corner_shape(&self) -> Option<RoundedCornerShape>

pub fn with_chain_guard(self, handle: ModifierChainHandle) -> ModifierNodeSlices

pub fn debug_stats(&self) -> ModifierNodeSlicesDebugStats

pub fn clear(&mut self)

Resets the slice collection for reuse, retaining vector capacity.
