Implementations

impl SharedArrayBuffer

pub fn new(length: u32) -> SharedArrayBuffer

The SharedArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer, similar to the ArrayBuffer object, but in a way that they can be used to create views on shared memory. Unlike an ArrayBuffer, a SharedArrayBuffer cannot become detached.

MDN documentation

impl SharedArrayBuffer

pub fn byte_length(&self) -> u32

The byteLength accessor property represents the length of an SharedArrayBuffer in bytes. This is established when the SharedArrayBuffer is constructed and cannot be changed.

MDN documentation

impl SharedArrayBuffer

pub fn slice(&self, begin: u32) -> SharedArrayBuffer

The slice() method returns a new SharedArrayBuffer whose contents are a copy of this SharedArrayBuffer’s bytes from begin, inclusive, up to end, exclusive.

MDN documentation

impl SharedArrayBuffer

pub fn slice_with_end(&self, begin: u32, end: u32) -> SharedArrayBuffer

Like slice() but with the end argument.

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.
