Struct GridPlacementModifier 

pub struct GridPlacementModifier {
    pub placement: GridPlacement,
}

Modifier that specifies the column and row placement of a view inside a Grid layout.

Fields

placement: GridPlacement

The grid placement settings containing column/row indexes and spans.

Trait Implementations

impl Clone for GridPlacementModifier

fn clone(&self) -> GridPlacementModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GridPlacementModifier

impl Debug for GridPlacementModifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for GridPlacementModifier

impl PartialEq for GridPlacementModifier

fn eq(&self, other: &GridPlacementModifier) -> 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.

impl StructuralPartialEq for GridPlacementModifier

impl ViewModifier for GridPlacementModifier

fn modify<V: View>(self, content: V) -> impl View

Wraps the child view in a ModifiedView using this modifier.

fn get_grid_placement(&self) -> Option<GridPlacement>

Exposes the grid placement metadata to parent layout engines.

fn render(&self, _renderer: &mut dyn Renderer, _rect: Rect)

Core rendering hook called before child views.

fn post_render(&self, _renderer: &mut dyn Renderer, _rect: Rect)

Cleanup hook called after child views.

fn render_view<V: View>( &self, view: &V, renderer: &mut dyn Renderer, rect: Rect, )

Allows a modifier to completely override or wrap the rendering of its child. Default implementation performs a standard push -> transform -> render child -> pop sequence.

fn transform_rect(&self, rect: Rect) -> Rect

fn transform_proposal(&self, proposal: SizeProposal) -> SizeProposal

Allows a modifier to transform the layout proposal before it reaches the child.

fn transform_size(&self, size: Size) -> Size

Allows a modifier to transform the resulting size from the child.

fn measure_view<V: View>( &self, view: &V, renderer: &mut dyn Renderer, proposal: SizeProposal, ) -> Size

Measure hook that coordinates size propagation.

fn child_flex_weight<V: View>(&self, view: &V) -> f32

Allows a modifier to override or pass through the child’s flex weight.

fn layout(&self) -> Option<&dyn LayoutView>
