[][src]Struct js_sys::Boolean

#[repr(transparent)]
pub struct Boolean { /* fields omitted */ }

Methods

impl Boolean[src]

pub fn new(value: &JsValue) -> Boolean[src]

Deprecated:

recommended to use Boolean::from instead

The Boolean() constructor creates an object wrapper for a boolean value.

MDN documentation

impl Boolean[src]

pub fn value_of(&self) -> bool[src]

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

MDN documentation

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.

MDN documentation

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).

MDN documentation

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

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[src]

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

MDN documentation

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.

MDN documentation

pub fn to_string(&self) -> JsString[src]

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

MDN documentation

pub fn value_of(&self) -> Object[src]

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