Struct MotionTrack 

pub struct MotionTrack {
    pub property: MotionPropertyId,
    pub phase: MotionPhase,
    pub from: MotionStartValue,
    pub to: MotionExpr,
    pub transition: MotionTransition,
}

A single declarative animation from a start value to a target expression.

Tracks are grouped by Motion or Presence and synchronized into the runtime. Later tracks targeting the same property and phase win when widget presets are composed.

use fission::motion::{
    px, MotionPropertyId, MotionStartValue, MotionTrack, MotionTransition, MotionEasing,
};

let slide = MotionTrack::composite(
    MotionPropertyId::TranslateY,
    MotionStartValue::Explicit(px(16.0)),
    px(0.0),
)
.transition(MotionTransition::tween(160, MotionEasing::EaseOut));

Fields

property: MotionPropertyId

Property affected by this track.

phase: MotionPhase

Rendering phase affected by this track.

from: MotionStartValue

Source value for a newly synchronized target.

to: MotionExpr

Target expression evaluated by the runtime.

transition: MotionTransition

Timing model for this track.

Implementations

impl MotionTrack

pub fn composite( property: MotionPropertyId, from: MotionStartValue, to: MotionExpr, ) -> Self

Creates a compositor-phase track for transform or opacity properties.

pub fn transition(self, transition: MotionTransition) -> Self

Replaces the track’s timing model.

Trait Implementations

impl Clone for MotionTrack

fn clone(&self) -> MotionTrack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MotionTrack

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MotionTrack

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MotionTrack

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
