Struct Morph 

pub struct Morph { /* private fields */ }

An animation between two RoundedPolygons of any structure: both outlines cut into matching curves. See androidx.graphics.shapes.Morph.

Implementations

impl Morph

pub fn new(start: &RoundedPolygon, end: &RoundedPolygon) -> Self

Match start and end. This measures both outlines, so hold on to the result: ShapeKind::morph_to keeps one per pair of Material shapes.

pub fn with_matching( start: &RoundedPolygon, end: &RoundedPolygon, matching: MorphMatching, ) -> Self

Self::new, matching the outlines by matching.

pub fn len(&self) -> usize

How many curves the outline has at any progress.

pub fn is_empty(&self) -> bool

Whether the morph has no curves. Polygons always give it at least one.

pub fn for_each_cubic(&self, progress: f32, each: impl FnMut(&Cubic))

Visit the outline at progress, without allocating: 0 is the start shape, 1 the end shape, and values beyond them extrapolate, for a spring’s overshoot.

pub fn as_cubics(&self, progress: f32) -> Vec<Cubic>

The outline at progress, closed exactly on its first anchor.

pub fn bounds(&self, approximate: bool) -> [f32; 4]

The box covering both shapes’ RoundedPolygon::bounds.

pub fn max_bounds(&self) -> [f32; 4]

The box covering both shapes’ RoundedPolygon::max_bounds.
