Trait Implementations

impl LayoutView for AspectRatio

fn size_that_fits( &self, proposal: SizeProposal, subviews: &[&dyn LayoutView], cache: &mut LayoutCache, ) -> Size

Propose a size for this view given the available space

fn place_subviews( &self, bounds: Rect, subviews: &mut [&mut dyn LayoutView], cache: &mut LayoutCache, )

Place subviews within the given bounds

fn flex_weight(&self) -> f32

Returns the flex weight of this view (default is 0.0, which means fixed/intrinsic)

fn view_hash(&self) -> u64

Returns a persistent unique identifier for this view to enable Layout View Transitions. Return 0 (default) to disable layout animations for this node.

fn changed(&self) -> bool

Return true when this view’s layout may have changed since the last pass.

fn debug_layout(&self, indent: usize) -> String

Return a debug representation of this layout subtree. The indent parameter controls the indentation level for nested display.
