Trait Implementations

impl Clone for TextOptions

fn clone(&self) -> TextOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<TextOptions> for JsValue

fn from(value: TextOptions) -> Self

Converts to this type from the input type.

impl FromWasmAbi for TextOptions

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 TextOptions

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 TextOptions

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<TextOptions>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for TextOptions

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 TextOptions

fn none() -> Self::Abi

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

impl RefFromWasmAbi for TextOptions

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<TextOptions>

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 TextOptions

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<TextOptions>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for TextOptions

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 TextOptions

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

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

impl VectorIntoWasmAbi for TextOptions

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

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

impl WasmDescribe for TextOptions

fn describe()

impl WasmDescribeVector for TextOptions

fn describe_vector()
