Struct js_sys::SyntaxError

#[repr(transparent)]
pub struct SyntaxError { /* fields omitted */ }

A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

Methods

impl SyntaxError

pub fn new(message: &str) -> SyntaxError

A SyntaxError is thrown when the JavaScript engine encounters tokens or token order that does not conform to the syntax of the language when parsing code.

Methods from Deref<Target = Error>

pub fn message(&self) -> JsString

The message property is a human-readable description of the error.

MDN documentation

pub fn set_message(&self, message: &str)

pub fn name(&self) -> JsString

The name property represents a name for the type of error. The initial value is "Error".

MDN documentation

pub fn set_name(&self, name: &str)

pub fn to_string(&self) -> JsString

The toString() method returns a string representing the specified Error object

impl Clone for SyntaxError

fn clone(&self) -> SyntaxError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxError

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

Formats the value using the given formatter.

impl Deref for SyntaxError

type Target = Error

The resulting type after dereferencing.

fn deref(&self) -> &Error

Dereferences the value.

impl FromWasmAbi for SyntaxError

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 SyntaxError

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 SyntaxError

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 SyntaxError

fn describe()

impl OptionIntoWasmAbi for SyntaxError

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 SyntaxError

fn none() -> Self::Abi

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

impl OptionFromWasmAbi for SyntaxError

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 RefFromWasmAbi for SyntaxError

type Abi = <JsValue as RefFromWasmAbi>::Abi

The wasm ABI type references to Self are recovered from.

type Anchor = ManuallyDrop<SyntaxError>

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, extra: &mut dyn Stack) -> Self::Anchor

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

impl JsCast for SyntaxError

fn instanceof(val: &JsValue) -> bool

Performs a dynamic instanceof check to see whether the JsValue provided is an instance of this type.
