A JavaScript object (ECMA-262, 4.3.3)

Implementations

`impl Object`[src]

`pub fn new<'s>(scope: &mut HandleScope<'s>) -> Local<'s, Object>`[src]

Creates an empty object.

`pub fn with_prototype_and_properties<'s>( scope: &mut HandleScope<'s>, prototype_or_null: Local<'s, Value>, names: &[Local<'_, Name>], values: &[Local<'_, Value>] ) -> Local<'s, Object>`[src]

Creates a JavaScript object with the given properties, and the given prototype_or_null (which can be any JavaScript value, and if it's null, the newly created object won't have a prototype at all). This is similar to Object.create(). All properties will be created as enumerable, configurable and writable properties.

`pub fn set( &self, scope: &mut HandleScope<'_>, key: Local<'_, Value>, value: Local<'_, Value> ) -> Option<bool>`[src]

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

`pub fn set_index( &self, scope: &mut HandleScope<'_>, index: u32, value: Local<'_, Value> ) -> Option<bool>`[src]

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

`pub fn set_prototype( &self, scope: &mut HandleScope<'_>, prototype: Local<'_, Value> ) -> Option<bool>`[src]

Set the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

`pub fn create_data_property( &self, scope: &mut HandleScope<'_>, key: Local<'_, Name>, value: Local<'_, Value> ) -> Option<bool>`[src]

Implements CreateDataProperty (ECMA-262, 7.3.4).

Defines a configurable, writable, enumerable property with the given value on the object unless the property already exists and is not configurable or the object is not extensible.

Returns true on success.

`pub fn define_own_property( &self, scope: &mut HandleScope<'_>, key: Local<'_, Name>, value: Local<'_, Value>, attr: PropertyAttribute ) -> Option<bool>`[src]

Implements DefineOwnProperty.

In general, CreateDataProperty will be faster, however, does not allow for specifying attributes.

Returns true on success.

`pub fn get<'s>( &self, scope: &mut HandleScope<'s>, key: Local<'_, Value> ) -> Option<Local<'s, Value>>`[src]

`pub fn get_index<'s>( &self, scope: &mut HandleScope<'s>, index: u32 ) -> Option<Local<'s, Value>>`[src]

`pub fn get_prototype<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, Value>>`[src]

Get the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

`pub fn set_accessor( &self, scope: &mut HandleScope<'_>, name: Local<'_, Name>, getter: impl for<'s> MapFnTo<AccessorNameGetterCallback<'s>> ) -> Option<bool>`[src]

Note: SideEffectType affects the getter only, not the setter.

`pub fn set_accessor_with_setter( &self, scope: &mut HandleScope<'_>, name: Local<'_, Name>, getter: impl for<'s> MapFnTo<AccessorNameGetterCallback<'s>>, setter: impl for<'s> MapFnTo<AccessorNameSetterCallback<'s>> ) -> Option<bool>`[src]

`pub fn creation_context<'s>( &self, scope: &mut HandleScope<'s> ) -> Local<'s, Context>`[src]

Returns the context in which the object was created.

`pub fn get_own_property_names<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, Array>>`[src]

This function has the same functionality as GetPropertyNames but the returned array doesn't contain the names of properties from prototype objects.

`pub fn get_property_names<'s>( &self, scope: &mut HandleScope<'s> ) -> Option<Local<'s, Array>>`[src]

Returns an array containing the names of the filtered properties of this object, including properties from prototype objects. The array returned by this method contains the same values as would be enumerated by a for-in statement over this object.

`pub fn has<'s>( &self, scope: &mut HandleScope<'s>, key: Local<'_, Value> ) -> Option<bool>`[src]

`pub fn has_index<'s>( &self, scope: &mut HandleScope<'s>, index: u32 ) -> Option<bool>`[src]

`pub fn delete<'s>( &self, scope: &mut HandleScope<'s>, key: Local<'_, Value> ) -> Option<bool>`[src]

`pub fn delete_index<'s>( &self, scope: &mut HandleScope<'s>, index: u32 ) -> Option<bool>`[src]

Methods from Deref<Target = Value>

`pub fn is_undefined(&self) -> bool`[src]

Returns true if this value is the undefined value. See ECMA-262 4.3.10.

Returns true if this value is the null value. See ECMA-262 4.3.11.

`pub fn is_null_or_undefined(&self) -> bool`[src]

Returns true if this value is either the null or the undefined value. See ECMA-262 4.3.11. and 4.3.12
