[−][src]Struct sauron::prelude::js_sys::WebAssembly::Instance
A WebAssembly.Instance
object is a stateful, executable instance
of a WebAssembly.Module
. Instance objects contain all the exported
WebAssembly functions that allow calling into WebAssembly code from
JavaScript.
Implementations
impl Instance
[src]
pub fn new(module: &Module, imports: &Object) -> Result<Instance, JsValue>
[src]
The WebAssembly.Instance()
constructor function can be called to
synchronously instantiate a given WebAssembly.Module
object. However, the primary way to get an Instance
is through the
asynchronous WebAssembly.instantiateStreaming()
function.
impl Instance
[src]
pub fn exports(&self) -> Object
[src]
The exports
readonly property of the WebAssembly.Instance
object
prototype returns an object containing as its members all the
functions exported from the WebAssembly module instance, to allow
them to be accessed and used by JavaScript.
Methods from Deref<Target = Object>
pub fn constructor(&self) -> Function
[src]
The constructor property returns a reference to the Object
constructor
function that created the instance object.
pub fn has_own_property(&self, property: &JsValue) -> bool
[src]
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
pub fn is_prototype_of(&self, value: &JsValue) -> bool
[src]
The isPrototypeOf()
method checks if an object exists in another
object's prototype chain.
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
[src]
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
pub fn to_locale_string(&self) -> JsString
[src]
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
pub fn to_string(&self) -> JsString
[src]
The toString()
method returns a string representing the object.
pub fn value_of(&self) -> Object
[src]
The valueOf()
method returns the primitive value of the
specified object.

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. Read more
