Trait Implementations

impl<'js> JsClass<'js> for RustFunction<'js>

const NAME: &'static str = "RustFunction"

The name the constructor has in JavaScript

const KIND: ClassKind = ClassKind::Callable

The kind of this class (plain, callable, or exotic).

type Mutable = Readable

Can the type be mutated while a JavaScript value.

fn prototype(ctx: &Ctx<'js>) -> Result<Option<Object<'js>>>

Returns the class prototype,

fn constructor(_ctx: &Ctx<'js>) -> Result<Option<Constructor<'js>>>

Returns a predefined constructor for this specific class type if there is one.

fn call<'a>( this: &JsCell<'js, Self>, params: Params<'a, 'js>, ) -> Result<Value<'js>>

The function which will be called if Self::KIND is ClassKind::Callable and an object with this class is called as if it is a function.

fn exotic_get_property( this: &JsCell<'js, Self>, ctx: &Ctx<'js>, _atom: Atom<'js>, _receiver: Value<'js>, ) -> Result<Value<'js>>

The function which will be called if a get property is performed on an object with this class
