Struct Inertia 

pub struct Inertia { /* private fields */ }

Scalar inertia animation.

Implementations

impl Inertia

pub fn new( position: f32, velocity: f32, friction: f32, min_velocity: f32, ) -> Self

Create inertia with initial position, velocity, friction, and min velocity.

pub fn with_preset( position: f32, velocity: f32, preset: &str, ) -> Result<Inertia, JsValue>

Use a named preset: smooth, snappy, or heavy.

pub fn set_bounds(&self, min: f32, max: f32)

Set inclusive bounds.

pub fn kick(&self, velocity: f32)

Start from a new velocity.

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

Advance by dt seconds.

pub fn position(&self) -> f32

Current position.

pub fn velocity(&self) -> f32

Current velocity.

pub fn snap_to(&self, position: f32)

Snap instantly.

pub fn is_settled(&self) -> bool

Whether inertia has settled.

Trait Implementations

impl Clone for Inertia

fn clone(&self) -> Inertia

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Inertia

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

Formats the value using the given formatter.

impl From<Inertia> for JsValue

fn from(value: Inertia) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Inertia

type Abi = WasmPtr<WasmRefCell<Inertia>>

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 Inertia

type Abi = WasmPtr<WasmRefCell<Inertia>>

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 Inertia

type Abi = WasmPtr<WasmRefCell<Inertia>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Inertia>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Inertia

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 Inertia

fn none() -> Self::Abi

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

impl RefFromWasmAbi for Inertia

type Abi = WasmPtr<WasmRefCell<Inertia>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Inertia>

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 Inertia

type Abi = WasmPtr<WasmRefCell<Inertia>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Inertia>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for Inertia

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 Inertia

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

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

impl VectorIntoWasmAbi for Inertia

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

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

impl WasmDescribe for Inertia

fn describe()

impl WasmDescribeVector for Inertia

fn describe_vector()
