impl LayoutView for ZStack
Source§fn size_that_fits(
&self,
proposal: SizeProposal,
subviews: &[&dyn LayoutView],
cache: &mut LayoutCache,
) -> Size
fn size_that_fits( &self, proposal: SizeProposal, subviews: &[&dyn LayoutView], cache: &mut LayoutCache, ) -> Size
Propose a size for this view given the available space
Source§fn place_subviews(
&self,
bounds: Rect,
subviews: &mut [&mut dyn LayoutView],
cache: &mut LayoutCache,
)
fn place_subviews( &self, bounds: Rect, subviews: &mut [&mut dyn LayoutView], cache: &mut LayoutCache, )
Place subviews within the given bounds
Source§fn flex_weight(&self) -> f32
fn flex_weight(&self) -> f32
Returns the flex weight of this view (default is 0.0, which means fixed/intrinsic)
Source§fn view_hash(&self) -> u64
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.
Source§fn changed(&self) -> bool
fn changed(&self) -> bool
Return true when this view’s layout may have changed since the last pass. Read more
Source§fn debug_layout(&self, indent: usize) -> String
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.Auto Trait Implementations§

Source§fn into_any(self: Box<T>) -> Box<dyn Any>
fn into_any(self: Box<T>) -> Box<dyn Any>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.Source§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.Source§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
