Struct OpacityModifier 

pub struct OpacityModifier {
    pub opacity: f32,
}

OpacityModifier fades this view and all its descendants to the given alpha. The renderer is expected to honour push_opacity/pop_opacity on the Renderer trait.

Fields

opacity: f32

Trait Implementations

impl Clone for OpacityModifier

fn clone(&self) -> OpacityModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OpacityModifier

impl Debug for OpacityModifier

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

Formats the value using the given formatter.

impl PartialEq for OpacityModifier

fn eq(&self, other: &OpacityModifier) -> 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 OpacityModifier

impl ViewModifier for OpacityModifier

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

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 get_grid_placement(&self) -> Option<GridPlacement>

Returns the grid placement configuration if this modifier defines one.

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>
