Enum SurfaceMotion 

pub enum SurfaceMotion {
    Default,
    Fade,
    Scale,
    SlideX(f32),
    SlideY(f32),
    Pop,
    Composition(Vec<SurfaceMotion>),
    Custom {
        enter: Vec<MotionTrack>,
        exit: Vec<MotionTrack>,
        keep_rendered: bool,
    },
}

Generic surface motion preset used by custom widgets and framework internals.

Built-in widgets expose widget-specific motion enums instead. Use SurfaceMotion when authoring your own widget that needs a simple enter/exit surface animation without defining a full public enum.

Variants

Default

Curated default: fade plus scale.

Fade

Fade opacity in.

Scale

Scale from slightly smaller to normal size.

SlideX(f32)

Slide horizontally from the given pixel offset.

SlideY(f32)

Slide vertically from the given pixel offset.

Pop

Compound fade plus scale preset.

Composition(Vec<SurfaceMotion>)

Ordered composition of surface motion atoms.

Custom

Caller-provided native tracks.

Fields

enter: Vec<MotionTrack>

Enter tracks.

exit: Vec<MotionTrack>

Exit tracks.

keep_rendered: bool

Whether the child stays rendered after exit completes.

Implementations

impl SurfaceMotion

pub fn compose(items: impl IntoIterator<Item = Self>) -> Self

Flattens and normalizes an ordered composition.

pub fn enter_tracks(&self) -> Vec<MotionTrack>

Lowers this preset into enter tracks.

pub fn exit_tracks(&self) -> Vec<MotionTrack>

Lowers this preset into exit tracks.

pub fn keep_rendered(&self) -> bool

Returns whether this preset requests persistent rendering after exit.

Trait Implementations

impl Add for SurfaceMotion

type Output = SurfaceMotion

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for SurfaceMotion

fn clone(&self) -> SurfaceMotion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurfaceMotion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SurfaceMotion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SurfaceMotion

fn eq(&self, other: &SurfaceMotion) -> 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 Serialize for SurfaceMotion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
