Expand description

The trait of all object types.

Provided methods

Gets a property from a JavaScript object that may be undefined and attempts to downcast the value if it existed.

Gets a property from a JavaScript object as a JsValue.

If a getter is defined on the object, it will be called.

Gets a property from a JavaScript object and attempts to downcast as a specific type. Equivalent to calling obj.get(&mut cx)?.downcast_or_throw(&mut cx).

Throws an exception if the value is a different type.

This is supported on crate feature napi-6 only.
