Enum DisplayNamesFallback 

#[non_exhaustive]
pub enum DisplayNamesFallback {
    Code = 0,
    None = 1,
}

Fallback for Intl.DisplayNames.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Code = 0

None = 1

Implementations

impl DisplayNamesFallback

pub fn from_js_value(obj: &JsValue) -> Option<DisplayNamesFallback>

Trait Implementations

impl Clone for DisplayNamesFallback

fn clone(&self) -> DisplayNamesFallback

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DisplayNamesFallback

impl Debug for DisplayNamesFallback

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Eq for DisplayNamesFallback

impl From<DisplayNamesFallback> for JsValue

fn from(val: DisplayNamesFallback) -> JsValue

Converts to this type from the input type.

impl FromWasmAbi for DisplayNamesFallback

type Abi = u32

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

unsafe fn from_abi(val: u32) -> DisplayNamesFallback

Recover a Self from Self::Abi.

impl IntoWasmAbi for DisplayNamesFallback

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 NullableFromWasmAbi for DisplayNamesFallback

fn is_null(val: &<DisplayNamesFallback as MaybeFromWasmAbi>::MaybeAbi) -> bool

Tests the ABI value for Nullable::Null.

impl NullableIntoWasmAbi for DisplayNamesFallback

fn null() -> <DisplayNamesFallback as MaybeIntoWasmAbi>::MaybeAbi

Returns the ABI value for Nullable::Null, which JS reads as null.

impl OptionFromWasmAbi for DisplayNamesFallback

fn is_none(val: &u32) -> 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 DisplayNamesFallback

fn none() -> <DisplayNamesFallback as IntoWasmAbi>::Abi

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

impl PartialEq for DisplayNamesFallback

fn eq(&self, other: &DisplayNamesFallback) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl StructuralPartialEq for DisplayNamesFallback

impl TryFromJsValue for DisplayNamesFallback

fn try_from_js_value_ref(value: &JsValue) -> Option<DisplayNamesFallback>

Performs the conversion.

const NULLABLE: bool = false

Whether Self accepts null as a distinct value space, as Nullable<T> does. An enclosing Option then passes null through instead of reading it as None, so Option<T> is itself nullable exactly when T is not. JsValue does not set this: it accepts null as one value among all of them, not as a distinct space, and Option<JsValue> reads it as None like the ABI does. This is the JS-value side of NullableFromWasmAbi, which claims null at the ABI.

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

Performs the conversion.

impl VectorFromWasmAbi for DisplayNamesFallback

type Abi = WasmSlice

unsafe fn vector_from_abi(js: WasmSlice) -> Box<[DisplayNamesFallback]>

impl VectorIntoWasmAbi for DisplayNamesFallback

type Abi = WasmSlice

fn vector_into_abi(vector: Box<[DisplayNamesFallback]>) -> WasmSlice

impl VectorRefIntoWasmAbi for DisplayNamesFallback

fn slice_into_abi(slice: &[DisplayNamesFallback]) -> WasmSlice
