Trait Implementations

impl Default for FastCache

fn default() -> Self

Returns the “default value” for a type.

impl From<FastCache> for JsValue

fn from(value: FastCache) -> Self

Converts to this type from the input type.

impl FromWasmAbi for FastCache

type Abi = u32

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

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for FastCache

type Abi = u32

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

fn into_abi(self) -> u32

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

impl LongRefFromWasmAbi for FastCache

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<FastCache>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for FastCache

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 FastCache

fn none() -> Self::Abi

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

impl RefFromWasmAbi for FastCache

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<FastCache>

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) -> Self::Anchor

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

impl RefMutFromWasmAbi for FastCache

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<FastCache>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for FastCache

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value(value: JsValue) -> Result<Self, Self::Error>

Performs the conversion.

impl VectorFromWasmAbi for FastCache

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[FastCache]>

impl VectorIntoJsValue for FastCache

fn vector_into_jsvalue(vector: Box<[FastCache]>) -> JsValue

impl VectorIntoWasmAbi for FastCache

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[FastCache]>) -> Self::Abi

impl WasmDescribe for FastCache

fn describe()

impl WasmDescribeVector for FastCache

fn describe_vector()

impl SupportsConstructor for FastCache

impl SupportsInstanceProperty for FastCache

impl SupportsStaticProperty for FastCache
