Trait Implementations

impl AsRef<JsValue> for DomStringMap

fn as_ref(&self) -> &JsValue

Performs the conversion.

impl AsRef<Object> for DomStringMap

fn as_ref(&self) -> &Object

Performs the conversion.

impl Clone for DomStringMap

fn clone(&self) -> DomStringMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<JsValue> for DomStringMap

fn from(obj: JsValue) -> DomStringMap

Performs the conversion.

impl From<DomStringMap> for JsValue

fn from(obj: DomStringMap) -> JsValue

Performs the conversion.

impl From<DomStringMap> for Object

fn from(obj: DomStringMap) -> Object

Performs the conversion.

impl Debug for DomStringMap

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

Formats the value using the given formatter.

impl Deref for DomStringMap

type Target = Object

The resulting type after dereferencing.

fn deref(&self) -> &Object

Dereferences the value.

impl WasmDescribe for DomStringMap

fn describe()

impl IntoWasmAbi for DomStringMap

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 DomStringMap

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 FromWasmAbi for DomStringMap

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 OptionFromWasmAbi for DomStringMap

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 RefFromWasmAbi for DomStringMap

type Abi = <JsValue as RefFromWasmAbi>::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<DomStringMap>

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.

impl OptionIntoWasmAbi for DomStringMap

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 DomStringMap

fn none() -> Self::Abi

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

impl JsCast for DomStringMap

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.
