Implementations

source

impl JsObject

source

pub fn empty() -> Self

Create a new empty JsObject, with prototype set to JsValue::Null and data set to ObjectData::ordinary

source

pub fn from_proto_and_data<O: Into<Option<Self>>>(
prototype: O,
data: ObjectData
) -> Self

The more general form of OrdinaryObjectCreate and MakeBasicObject.

Create a JsObject and automatically set its internal methods and internal slots from the data provided.

source

pub fn borrow(&self) -> Ref<'_, Object>

Immutably borrows the Object.

The borrow lasts until the returned Ref exits scope. Multiple immutable borrows can be taken out at the same time.

Panics

Panics if the object is currently mutably borrowed.

source

pub fn borrow_mut(&self) -> RefMut<'_, Object, Object>

The borrow lasts until the returned RefMut exits scope. The object cannot be borrowed while this borrow is active.

Panics

Panics if the object is currently borrowed.

source

pub fn try_borrow(&self) -> StdResult<Ref<'_, Object>, BorrowError>

Immutably borrows the Object, returning an error if the value is currently mutably borrowed.

The borrow lasts until the returned GcCellRef exits scope. Multiple immutable borrows can be taken out at the same time.
