Implementations

impl Table

pub fn new(table_descriptor: &Object) -> Result<Table, JsValue>

The WebAssembly.Table() constructor creates a new Table object of the given size and element type.

MDN documentation

impl Table

pub fn length(&self) -> u32

The length prototype property of the WebAssembly.Table object returns the length of the table, i.e. the number of elements in the table.

MDN documentation

impl Table

pub fn get(&self, index: u32) -> Result<Function, JsValue>

The get() prototype method of the WebAssembly.Table() object retrieves a function reference stored at a given index.

MDN documentation

impl Table

pub fn grow(&self, additional_capacity: u32) -> Result<u32, JsValue>

The grow() prototype method of the WebAssembly.Table object increases the size of the Table instance by a specified number of elements.

MDN documentation

impl Table

pub fn set(&self, index: u32, function: &Function) -> Result<(), JsValue>

The set() prototype method of the WebAssembly.Table object mutates a reference stored at a given index to a different value.

MDN documentation

Methods from Deref<Target = Object>

pub fn constructor(&self) -> Function

The constructor property returns a reference to the Object constructor function that created the instance object.

MDN documentation

pub fn has_own_property(&self, property: &JsValue) -> bool

The hasOwnProperty() method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

MDN documentation

pub fn is_prototype_of(&self, value: &JsValue) -> bool

The isPrototypeOf() method checks if an object exists in another object's prototype chain.

MDN documentation

pub fn property_is_enumerable(&self, property: &JsValue) -> bool

The propertyIsEnumerable() method returns a Boolean indicating whether the specified property is enumerable.

MDN documentation

pub fn to_locale_string(&self) -> JsString

The toLocaleString() method returns a string representing the object. This method is meant to be overridden by derived objects for locale-specific purposes.

MDN documentation

pub fn to_string(&self) -> JsString

The toString() method returns a string representing the object.

MDN documentation

pub fn value_of(&self) -> Object

The valueOf() method returns the primitive value of the specified object.
