Struct ScrollDriver 

pub struct ScrollDriver { /* private fields */ }

Scroll position driver for scroll-linked animations.

Implementations

impl ScrollDriver

pub fn new(min: f32, max: f32) -> Self

Create a scroll driver with a min and max scroll position.

pub fn add_tween(&self, tween: &Tween)

Register a tween.

pub fn set_position(&self, position: f32)

Set the current scroll position.

pub fn progress(&self) -> f32

Current normalized scroll progress.

pub fn position(&self) -> f32

Current scroll position.

pub fn animation_count(&self) -> usize

Number of registered animations.

pub fn clear_completed(&self)

Remove completed animations.

Trait Implementations

impl Clone for ScrollDriver

fn clone(&self) -> ScrollDriver

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollDriver

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

Formats the value using the given formatter.

impl From<ScrollDriver> for JsValue

fn from(value: ScrollDriver) -> Self

Converts to this type from the input type.

impl FromWasmAbi for ScrollDriver

type Abi = WasmPtr<WasmRefCell<ScrollDriver>>

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 ScrollDriver

type Abi = WasmPtr<WasmRefCell<ScrollDriver>>

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 ScrollDriver

type Abi = WasmPtr<WasmRefCell<ScrollDriver>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<ScrollDriver>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for ScrollDriver

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 ScrollDriver

fn none() -> Self::Abi

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

impl RefFromWasmAbi for ScrollDriver

type Abi = WasmPtr<WasmRefCell<ScrollDriver>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<ScrollDriver>

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 ScrollDriver

type Abi = WasmPtr<WasmRefCell<ScrollDriver>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<ScrollDriver>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for ScrollDriver

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 ScrollDriver

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

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

impl VectorIntoWasmAbi for ScrollDriver

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

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