impl WasmDescribe for ImageBitmap

fn describe()

impl FromWasmAbi for ImageBitmap

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 ImageBitmap

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 ImageBitmap

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 OptionFromWasmAbi for ImageBitmap

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 ImageBitmap

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 ImageBitmap

fn none() -> Self::Abi

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

impl RefFromWasmAbi for ImageBitmap

type Abi = <JsValue as RefFromWasmAbi>::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<ImageBitmap>

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.
