Struct TweenBatch 

pub struct TweenBatch { /* private fields */ }

Batched scalar tween evaluator.

Implementations

impl TweenBatch

pub fn new() -> Self

Create an empty batch.

pub fn push( &mut self, from: f32, to: f32, duration: f32, easing: &str, ) -> Result<u32, JsValue>

Push a tween and return its batch index.

pub fn tick(&mut self, dt: f32)

Advance every tween by dt seconds.

pub fn value(&self, index: u32) -> Result<f32, JsValue>

Current value at index.

pub fn values(&self) -> Float32Array

All current values.

pub fn len(&self) -> usize

Number of tweens.

pub fn is_empty(&self) -> bool

Whether the batch is empty.

pub fn clear(&mut self)

Clear all tweens.

Trait Implementations

impl Clone for TweenBatch

fn clone(&self) -> TweenBatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TweenBatch

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

Formats the value using the given formatter.

impl Default for TweenBatch

fn default() -> TweenBatch

Returns the “default value” for a type.

impl From<TweenBatch> for JsValue

fn from(value: TweenBatch) -> Self

Converts to this type from the input type.

impl FromWasmAbi for TweenBatch

type Abi = WasmPtr<WasmRefCell<TweenBatch>>

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 TweenBatch

type Abi = WasmPtr<WasmRefCell<TweenBatch>>

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 TweenBatch

type Abi = WasmPtr<WasmRefCell<TweenBatch>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<TweenBatch>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for TweenBatch

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 TweenBatch

fn none() -> Self::Abi

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

impl RefFromWasmAbi for TweenBatch

type Abi = WasmPtr<WasmRefCell<TweenBatch>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<TweenBatch>

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 TweenBatch

type Abi = WasmPtr<WasmRefCell<TweenBatch>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<TweenBatch>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for TweenBatch

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 TweenBatch

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

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

impl VectorIntoWasmAbi for TweenBatch

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

fn vector_into_abi(vector: Box<[TweenBatch]>) -> Self::Abi
