Struct AnimationSegment 

pub struct AnimationSegment {
    pub duration: f32,
    pub anim_fn: for<'a> fn(&'a mut Ui, f32),
}

A single segment of the animation.

Defines the duration of a segment (in seconds), and a mutating function for the [Ui]. See Animation for details on how to construct an animation function.

Example

// A simple animation that fades the prior value out, and the new value in.
// Has a total time of `0.4` seconds with each segment taking a respective `0.2` seconds each.
const FADE_OUT: AnimationSegment = AnimationSegment::new(0.2, |ui, normal| ui.set_opacity(1.0 - normal));
const FADE_IN: AnimationSegment = AnimationSegment::new(0.2, |ui, normal| ui.set_opacity(normal));

const ANIM: Animation = Animation::from_segments(FADE_OUT, FADE_IN);

Fields

duration: f32

The duration of the animation, in seconds.

anim_fn: for<'a> fn(&'a mut Ui, f32)

The [Ui] mutating function for the given f32 normal.

Implementations

impl AnimationSegment

pub const fn new(duration: f32, anim_fn: for<'a> fn(&'a mut Ui, f32)) -> Self

Create a new AnimationSegment from the given duration and animation function.

pub fn duration(&self) -> f32

Get the animation duration.

pub fn duration_mut(&mut self) -> f32

pub fn anim_fn(&self) -> for<'a> fn(&'a mut Ui, f32)

Get the animation function.
