Implementations

impl Object

pub fn create( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.create( proto, [propertiesObject] )

Creates a new object from the provided prototype.

More information:

• ECMAScript reference

pub fn get_own_property_descriptor( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.getOwnPropertyDescriptor( object, property )

Returns an object describing the configuration of a specific property on a given object.

More information:

• ECMAScript reference
• MDN documentation

pub fn get_own_property_descriptors( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.getOwnPropertyDescriptors( object )

Returns all own property descriptors of a given object.

More information:

• ECMAScript reference
• MDN documentation

pub fn is(_: &JsValue, args: &[JsValue], _: &mut Context) -> JsResult<JsValue>

Uses the SameValue algorithm to check equality of objects

pub fn get_prototype_of( _: &JsValue, args: &[JsValue], ctx: &mut Context, ) -> JsResult<JsValue>

Get the prototype of an object.

pub fn set_prototype_of( _: &JsValue, args: &[JsValue], ctx: &mut Context, ) -> JsResult<JsValue>

Set the prototype of an object.

More information

pub fn is_prototype_of( this: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.prototype.isPrototypeOf( proto )

Check whether or not an object exists within another object’s prototype chain.

More information:

• ECMAScript reference
• MDN documentation

pub fn define_property( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Define a property in an object

pub fn define_properties( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.defineProperties( proto, [propertiesObject] )

Creates or update own properties to the object

More information:

• ECMAScript reference
• MDN documentation

pub fn value_of( this: &JsValue, _: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.prototype.valueOf()

More information:

• ECMAScript reference
• MDN documentation

pub fn to_string( this: &JsValue, _: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.prototype.toString()

This method returns a string representing the object.

More information:

• ECMAScript reference
• MDN documentation

pub fn has_own_property( this: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.prototype.hasOwnPrototype( property )

The method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

More information:

• ECMAScript reference
• MDN documentation

pub fn property_is_enumerable( this: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.prototype.propertyIsEnumerable( property )

This method returns a Boolean indicating whether the specified property is enumerable and is the object’s own property.

More information:

• ECMAScript reference
• MDN documentation

pub fn assign( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.assign( target, ...sources )

This method copies all enumerable own properties from one or more source objects to a target object. It returns the target object.

More information:

• ECMAScript reference
• MDN documentation

pub fn keys( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.keys( target )

This method returns an array of a given object’s own enumerable property names, iterated in the same order that a normal loop would.

More information:

• ECMAScript reference
• MDN documentation

pub fn values( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.values( target )

More information:

• ECMAScript reference
• MDN documentation

pub fn entries( _: &JsValue, args: &[JsValue], context: &mut Context, ) -> JsResult<JsValue>

Object.entries( target )

This method returns an array of a given object’s own enumerable string-keyed property [key, value] pairs. This is the same as iterating with a for…in loop, except that a for…in loop enumerates properties in the prototype chain as well).

More information:

• ECMAScript reference
• MDN documentation

Object.seal( target )
