Struct js_sys::WebAssembly::RuntimeError

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

The WebAssembly.RuntimeError() constructor creates a new WebAssembly RuntimeError object — the type that is thrown whenever WebAssembly specifies a trap.

Implementations

impl RuntimeError

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

The WebAssembly.RuntimeError() constructor creates a new WebAssembly RuntimeError object — the type that is thrown whenever WebAssembly specifies a trap.

MDN documentation

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
