Expand description
Implementations
The clear()
method removes all elements from a Set
object.
The size accessor property returns the number of elements in a Set
object.
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.
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.
The values()
method returns a new Iterator object that contains the
values for each element in the Set object in insertion order.
Methods from Deref<Target = Object>
The constructor property returns a reference to the Object
constructor
function that created the instance object.
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
The toString()
method returns a string representing the object.
The valueOf()
method returns the primitive value of the
specified object.

type Abi = <JsValue as RefFromWasmAbi>::Abi
type Abi = <JsValue as RefFromWasmAbi>::Abi
The wasm ABI type references to Self
are recovered from.
type Anchor = ManuallyDrop<Set>
type Anchor = ManuallyDrop<Set>
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
