Struct TransformModifier 

pub struct TransformModifier {
    pub translation: [f32; 2],
    pub scale: [f32; 2],
    pub rotation: f32,
}

TransformModifier applies a 2D transform (translation, scale, rotation) to its child. This modifier is “layout-neutral” and can be animated without re-running the layout engine.

Fields

translation: [f32; 2]

scale: [f32; 2]

rotation: f32

Implementations

impl TransformModifier

pub fn new() -> Self

pub fn translate(self, x: f32, y: f32) -> Self

pub fn scale(self, x: f32, y: f32) -> Self

pub fn rotate(self, radians: f32) -> Self

Trait Implementations

impl Clone for TransformModifier

fn clone(&self) -> TransformModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransformModifier

impl Debug for TransformModifier

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

Formats the value using the given formatter.

impl Default for TransformModifier

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TransformModifier

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

impl ViewModifier for TransformModifier

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

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 get_grid_placement(&self) -> Option<GridPlacement>

Returns the grid placement configuration if this modifier defines one.

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 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>
