Struct dodrio_js_api::JsRender

#[repr(transparent)]
pub struct JsRender { /* fields omitted */ }

A rendering component implemented in JavaScript.

The rendering API is a bit duck-typed: any JS object with a render method that returns a virtual DOM as JS values with the right shape works.

See JsRender::new for converting existing JS objects into JsRenders.

Methods

impl JsRender

pub fn new<O>(object: O) -> JsRender where
    O: Into<Object>, 

Convert a js_sys::Object into a JsRender.

The given object must have a render method that conforms to the duck-typed virtual DOM interface which is described in the crate-level documentation.

Trait Implementations

impl From<JsValue> for JsRender

fn from(obj: JsValue) -> JsRender

Performs the conversion.

impl From<JsRender> for JsValue

fn from(obj: JsRender) -> JsValue

impl Clone for JsRender

fn clone(&self) -> JsRender

Returns a copy of the value.

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

impl Debug for JsRender

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

impl JsCast for JsRender

fn instanceof(val: &JsValue) -> bool

Performs a dynamic instanceof check to see whether the JsValue provided is an instance of this type.

fn unchecked_from_js(val: JsValue) -> Self

Performs a zero-cost unchecked conversion from a JsValue into an instance of Self

fn unchecked_from_js_ref(val: &JsValue) -> &Self

Performs a zero-cost unchecked conversion from a &JsValue into an instance of &Self.

fn is_instance_of<T>(&self) -> bool where
    T: JsCast, 

Test whether this JS value is an instance of the type T.

fn dyn_into<T>(self) -> Result<T, Self> where
    T: JsCast, 

Performs a dynamic cast (checked at runtime) of this value into the target type T.

fn dyn_ref<T>(&self) -> Option<&T> where
    T: JsCast, 

Performs a dynamic cast (checked at runtime) of this value into the target type T.

fn unchecked_into<T>(self) -> T where
    T: JsCast, 

Performs a zero-cost unchecked cast into the specified type.

fn unchecked_ref<T>(&self) -> &T where
    T: JsCast, 

Performs a zero-cost unchecked cast into a reference to the specified type.

impl FromWasmAbi for JsRender

type Abi = <JsValue as FromWasmAbi>::Abi

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

unsafe fn from_abi(js: Self::Abi, extra: &mut dyn Stack) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for JsRender

type Abi = <JsValue as IntoWasmAbi>::Abi

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

fn into_abi(self, extra: &mut dyn Stack) -> Self::Abi

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

impl<'a> IntoWasmAbi for &'a JsRender

type Abi = <&'a JsValue as IntoWasmAbi>::Abi

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

fn into_abi(self, extra: &mut dyn Stack) -> Self::Abi

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

impl WasmDescribe for JsRender

fn describe()

impl OptionFromWasmAbi for JsRender

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 JsRender

fn none() -> Self::Abi

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

impl<'a> OptionIntoWasmAbi for &'a JsRender

fn none() -> Self::Abi

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

impl RefFromWasmAbi for JsRender

type Abi = <JsValue as RefFromWasmAbi>::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<JsRender>

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, extra: &mut dyn Stack) -> Self::Anchor

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