Struct Keyframes 

pub struct Keyframes { /* private fields */ }

A collection of property snapshots keyed by normalized offsets.

Keyframes is the compact, sampled representation used by timelines and the runtime. Build one with KeyframesBuilder.

Example

use aura_anim_iced::{Easing, KeyframesBuilder, Timing, property};

let keyframes = KeyframesBuilder::new()
    .with_timing(Timing::new(180.0).with_easing(Easing::EaseOut))
    .at(0.0, (property::OPACITY, 0.0))
    .at(0.0, (property::SCALE, 0.95))
    .at(1.0, (property::OPACITY, 1.0))
    .at(1.0, (property::SCALE, 1.0))
    .finish();

let sample = keyframes.sample_at(0.5).expect("active sample");

assert!(sample.find_property(&property::OPACITY.raw()).is_some());
assert!(sample.find_property(&property::SCALE.raw()).is_some());

Implementations

impl Keyframes

pub fn builder() -> KeyframesBuilder

Creates a keyframe builder.

pub fn is_empty(&self) -> bool

Returns true when this keyframe set has no property tracks.

pub fn track_count(&self) -> usize

Returns the number of property tracks in this keyframe set.

pub fn timing(&self) -> &Timing

Returns the timing attached to this keyframe set.

pub fn sample_at(&self, offset: f32) -> Option<PropertySnapshot>

Samples all property tracks at a normalized offset.

Trait Implementations

impl Clone for Keyframes

fn clone(&self) -> Keyframes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Keyframes

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

Formats the value using the given formatter.

impl Default for Keyframes

fn default() -> Keyframes

Returns the “default value” for a type.

impl From<Keyframes> for Track

fn from(value: Keyframes) -> Self

Converts to this type from the input type.

impl PartialEq for Keyframes

fn eq(&self, other: &Keyframes) -> 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.
