Struct ModifierNodeSlices 

pub struct ModifierNodeSlices { /* private fields */ }

Snapshot of modifier node slices that impact draw and pointer subsystems.

Implementations

impl ModifierNodeSlices

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

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

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

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<TextPanResolver>

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<Cell<Rect>>>

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) -> Self

pub fn debug_stats(&self) -> ModifierNodeSlicesDebugStats

pub fn clear(&mut self)

Resets the slice collection for reuse, retaining vector capacity.
