pub fn get_prototype<T>(&self) -> Result<T>

where T: NapiValue,

This returns the equivalent of Object.getPrototypeOf (which is not the same as the function’s prototype property).

pub fn define_properties(&mut self, properties: &[Property]) -> Result<()>

This method allows the efficient definition of multiple properties on a given object.

pub fn get_array_length(&self) -> Result<u32>

Perform is_array check before get the length if Object is not array, ArrayExpected error returned

pub fn get_array_length_unchecked(&self) -> Result<u32>

use this API if you can ensure this Object is Array

pub fn freeze(&mut self) -> Result<()>

pub fn seal(&mut self) -> Result<()>
