Enum TaskPriority 

#[non_exhaustive]
pub enum TaskPriority {
    UserBlocking = 0,
    UserVisible = 1,
    Background = 2,
}

The TaskPriority enum.

This API requires the following crate features to be activated: TaskPriority

This API is unstable and requires --cfg=web_sys_unstable_apis to be activated, as described in the wasm-bindgen guide

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.

UserBlocking = 0

UserVisible = 1

Background = 2

Implementations

impl TaskPriority

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

Trait Implementations

impl Clone for TaskPriority

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TaskPriority

impl Debug for TaskPriority

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

Formats the value using the given formatter.

impl Eq for TaskPriority

impl From<TaskPriority> for JsValue

fn from(val: TaskPriority) -> Self

Converts to this type from the input type.

impl FromWasmAbi for TaskPriority

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) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for TaskPriority

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 TaskPriority

fn is_null(val: &Self::MaybeAbi) -> bool

Tests the ABI value for Nullable::Null.

impl NullableIntoWasmAbi for TaskPriority

fn null() -> Self::MaybeAbi

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

impl OptionFromWasmAbi for TaskPriority

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 TaskPriority

fn none() -> Self::Abi

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

impl PartialEq for TaskPriority

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for TaskPriority

impl TryFromJsValue for TaskPriority

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

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 TaskPriority

type Abi = WasmSlice

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

impl VectorIntoWasmAbi for TaskPriority

type Abi = WasmSlice

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

impl VectorRefIntoWasmAbi for TaskPriority

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

impl VectorRefIntoWasmAbiSealed for TaskPriority

impl WasmDescribe for TaskPriority

fn describe()

impl WasmDescribeVector for TaskPriority
