Fields

properties: HashMap<PropertyKey, Rc<RefCell<Value>>>

constants: HashSet<String>

non_enumerable: HashSet<PropertyKey>

Tracks keys that should not be enumerated by Object.keys / Object.values.

non_writable: HashSet<PropertyKey>

Tracks keys that are non-writable (read-only)

non_configurable: HashSet<PropertyKey>

Tracks keys that are non-configurable

prototype: Option<Rc<RefCell<JSObjectData>>>

is_function_scope: bool

Implementations

impl JSObjectData

pub fn new() -> Self
