Implementations

impl Set[−]

pub fn add(&self, value: &JsValue) -> Set[−]

The add() method appends a new element with a specified value to the end of a Set object.

MDN documentation

impl Set[−]

pub fn clear(&self)[−]

The clear() method removes all elements from a Set object.

MDN documentation

impl Set[−]

pub fn delete(&self, value: &JsValue) -> bool[−]

The delete() method removes the specified element from a Set object.

MDN documentation

impl Set[−]

pub fn for_each(&self, callback: &mut dyn FnMut(JsValue, JsValue, Set))[−]

The forEach() method executes a provided function once for each value in the Set object, in insertion order.

MDN documentation

impl Set[−]

pub fn has(&self, value: &JsValue) -> bool[−]

The has() method returns a boolean indicating whether an element with the specified value exists in a Set object or not.

MDN documentation

impl Set[−]

pub fn new(init: &JsValue) -> Set[−]

The Set object lets you store unique values of any type, whether primitive values or object references.

MDN documentation

impl Set[−]

pub fn size(&self) -> u32[−]

The size accessor property returns the number of elements in a Set object.

MDN documentation

impl Set[−]

pub fn entries(&self) -> Iterator[−]

The entries() method returns a new Iterator object that contains an array of [value, value] for each element in the Set object, in insertion order. For Set objects there is no key like in Map objects. However, to keep the API similar to the Map object, each entry has the same value for its key and value here, so that an array [value, value] is returned.

MDN documentation

impl Set[−]

pub fn keys(&self) -> Iterator[−]

The keys() method is an alias for this method (for similarity with Map objects); it behaves exactly the same and returns values of Set elements.

MDN documentation

impl Set[−]

pub fn values(&self) -> Iterator[−]

The values() method returns a new Iterator object that contains the values for each element in the Set object in insertion order.

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.

MDN documentation
