Add a keyframe with easing applied to the following segment.

pub fn update(&self, dt: f32) -> bool

Advance by dt seconds.

pub fn value(&self) -> f32

Current value, or NaN if the track is empty.

pub fn value_at(&self, seconds: f32) -> f32

Value at an absolute time, or NaN if the track is empty.

pub fn duration(&self) -> f32

Track duration in seconds.

pub fn progress(&self) -> f32

Normalized track progress.

pub fn is_complete(&self) -> bool

Whether playback is complete.

pub fn reset(&self)

Trait Implementations

impl Clone for KeyframeTrack

fn clone(&self) -> KeyframeTrack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyframeTrack

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

Formats the value using the given formatter.

impl Default for KeyframeTrack

fn default() -> Self

Returns the “default value” for a type.

impl From<KeyframeTrack> for JsValue

fn from(value: KeyframeTrack) -> Self

Converts to this type from the input type.

impl FromWasmAbi for KeyframeTrack

type Abi = WasmPtr<WasmRefCell<KeyframeTrack>>

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for KeyframeTrack

type Abi = WasmPtr<WasmRefCell<KeyframeTrack>>

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for KeyframeTrack

type Abi = WasmPtr<WasmRefCell<KeyframeTrack>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<KeyframeTrack>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for KeyframeTrack

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for KeyframeTrack

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for KeyframeTrack

type Abi = WasmPtr<WasmRefCell<KeyframeTrack>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<KeyframeTrack>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for KeyframeTrack

type Abi = WasmPtr<WasmRefCell<KeyframeTrack>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<KeyframeTrack>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for KeyframeTrack

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for KeyframeTrack

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[KeyframeTrack]>

impl VectorIntoWasmAbi for KeyframeTrack

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi
