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

Implementations

impl Generator

pub fn next(&self, value: &JsValue) -> Result<JsValue, JsValue>

The next() method returns an object with two properties done and value. You can also provide a parameter to the next method to send a value to the generator.

MDN documentation

impl Generator

pub fn return_(&self, value: &JsValue) -> JsValue

The return() method returns the given value and finishes the generator.

MDN documentation

impl Generator

pub fn throw(&self, error: &Error) -> Result<JsValue, JsValue>

The throw() method resumes the execution of a generator by throwing an error into it and returns an object with two properties done and value.

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.
