ObjectData is the representation of an object in JavaScript

Fields

kind: ObjectKind

Kind

internal_slots: Box<HashMap<String, Value>>

Internal Slots

properties: Box<HashMap<String, Property>>

Properties

sym_properties: Box<HashMap<i32, Property>>

Symbol Properties

state: Option<Box<InternalStateCell>>

Some rust object that stores internal state

Implementations

impl Object

pub fn default() -> Self

Return a new ObjectData struct, with kind set to Ordinary

pub fn create(proto: Value) -> Object

ObjectCreate is used to specify the runtime creation of new ordinary objects

https://tc39.es/ecma262/#sec-objectcreate

pub fn get_internal_slot(&self, name: &str) -> Value

Utility function to get an immutable internal slot or Null

pub fn set_internal_slot(&mut self, name: &str, val: Value)

Utility function to set an internal slot

pub fn set_internal_method(&mut self, name: &str, val: NativeFunctionData)

Utility function to set an internal slot which is a function

pub fn set_method(&mut self, name: &str, val: NativeFunctionData)

Utility function to set a method on this object The native function will live in the properties field of the Object

pub fn from(value: &Value) -> Result<Self, ()>

pub fn get_prototype_of(&self) -> Value

Returns either the prototype or null https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-getprototypeof

pub fn set_prototype_of(&mut self, val: Value) -> bool

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-setprototypeof-v

pub fn is_extensible(&self) -> bool

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-isextensible

pub fn prevent_extensions(&mut self) -> bool

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-preventextensions

pub fn get_own_property(&self, prop: &Value) -> Property

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-getownproperty-p The specification returns a Property Descriptor or Undefined. These are 2 separate types and we can't do that here.

pub fn has_property(&self, val: &Value) -> bool

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-hasproperty-p

pub fn define_own_property(
    &mut self,
    property_key: String,
    desc: Property
) -> bool

pub fn delete(&mut self, prop_key: &Value) -> bool

pub fn get(&self, val: &Value) -> Value

pub fn set(&mut self, field: Value, val: Value) -> bool

[[Set]]
