[−][src]Struct js_sys::WebAssembly::Table
The WebAssembly.Table()
constructor creates a new Table
object
of the given size and element type.
Methods
impl Table
[src]
pub fn new(table_descriptor: &Object) -> Result<Table, JsValue>
[src]
The WebAssembly.Table()
constructor creates a new Table
object
of the given size and element type.
impl Table
[src]
pub fn length(&self) -> u32
[src]
The length
prototype property of the WebAssembly.Table
object
returns the length of the table, i.e. the number of elements in the
table.
impl Table
[src]
pub fn get(&self, index: u32) -> Result<Function, JsValue>
[src]
The get()
prototype method of the WebAssembly.Table()
object
retrieves a function reference stored at a given index.
impl Table
[src]
pub fn grow(&self, additional_capacity: u32) -> Result<u32, JsValue>
[src]
The grow()
prototype method of the WebAssembly.Table
object
increases the size of the Table
instance by a specified number of
elements.
impl Table
[src]
pub fn set(&self, index: u32, function: &Function) -> Result<(), JsValue>
[src]
The set()
prototype method of the WebAssembly.Table
object mutates a
reference stored at a given index to a different value.
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.
