impl Debug for IdbCursorWithValue

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

Formats the value using the given formatter.

impl Deref for IdbCursorWithValue

type Target = IdbCursor

The resulting type after dereferencing.

fn deref(&self) -> &IdbCursor

Dereferences the value.

impl FromWasmAbi for IdbCursorWithValue

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 IdbCursorWithValue

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 IdbCursorWithValue

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 IdbCursorWithValue

fn describe()

impl OptionIntoWasmAbi for IdbCursorWithValue

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 IdbCursorWithValue

fn none() -> Self::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<IdbCursorWithValue>

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.
