impl Debug for CanvasRenderingContext2d

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

Formats the value using the given formatter.

impl Deref for CanvasRenderingContext2d

type Target = Object

The resulting type after dereferencing.

fn deref(&self) -> &Object

impl FromWasmAbi for CanvasRenderingContext2d

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 CanvasRenderingContext2d

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 CanvasRenderingContext2d

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 CanvasRenderingContext2d

fn describe()

impl OptionFromWasmAbi for CanvasRenderingContext2d

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 CanvasRenderingContext2d

fn none() -> Self::Abi

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

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<CanvasRenderingContext2d>

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.
