}

Identifies the property a MotionTrack animates.

The property decides the default value, value unit, and shell binding used during rendering. Built-in properties are understood by Fission shells. MotionPropertyId::Custom is for widget-specific progress values that are consumed by custom renderers rather than by the standard compositor.

use fission::motion::{
    scalar, MotionPropertyId, MotionStartValue, MotionTrack,
};

let fade = MotionTrack::composite(
    MotionPropertyId::Opacity,
    MotionStartValue::Explicit(scalar(0.0)),
    scalar(1.0),
);

Variants

Opacity

Compositor opacity; scalar where 0.0 is transparent and 1.0 is opaque.

TranslateX

Horizontal compositor translation in logical pixels.

TranslateY

Vertical compositor translation in logical pixels.

Scale

Uniform compositor scale; scalar where 1.0 is unchanged size.

Rotation

Compositor rotation in degrees.

Width

Layout width in logical pixels.

Height

Layout height in logical pixels.

LayoutX

Absolute layout x-position in logical pixels.

LayoutY

Absolute layout y-position in logical pixels.

LayoutWidth

Layout snapshot width in logical pixels.

LayoutHeight

Layout snapshot height in logical pixels.

IntrinsicWidth

Intrinsic width of the tracked widget in logical pixels.

IntrinsicHeight

Intrinsic height of the tracked widget in logical pixels.

CornerRadius

Paint/layout corner radius in logical pixels.

BackgroundColor

Paint background color.

BorderColor

Paint border color.

TextColor

Paint text color.

Custom(Arc<str>)

Widget-defined property consumed by custom renderers or widget code.

Implementations

impl MotionPropertyId

pub fn opacity() -> Self

Convenience constructor for MotionPropertyId::Opacity.

pub fn translate_x() -> Self

Convenience constructor for MotionPropertyId::TranslateX.

pub fn translate_y() -> Self

Convenience constructor for MotionPropertyId::TranslateY.

pub fn scale() -> Self

Convenience constructor for MotionPropertyId::Scale.

pub fn rotation() -> Self

Convenience constructor for MotionPropertyId::Rotation.

pub fn custom(name: impl Into<String>) -> Self

Creates a widget-defined motion property.

Use a namespaced string such as "my_crate::chart_progress" to avoid collisions with other widgets.

pub fn default_value(&self) -> MotionValue

Returns the implicit starting value used when no runtime value exists.

pub fn default_scalar_value(&self) -> f32

Returns the default as a scalar-like value for compositor resolution.

Color and boolean defaults resolve to 0.0.

Trait Implementations

impl Clone for MotionPropertyId

fn clone(&self) -> MotionPropertyId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionPropertyId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MotionPropertyId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for MotionPropertyId

impl Hash for MotionPropertyId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MotionPropertyId

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
