return Array
of property names
sourcepub fn get_prototype<T>(&self) -> Result<T>where
T: NapiValue,
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).

T: NapiValue,

sourcepub fn define_properties(&mut self, properties: &[Property]) -> Result<()>
pub fn define_properties(&mut self, properties: &[Property]) -> Result<()>
This method allows the efficient definition of multiple properties on a given object.
sourcepub fn get_array_length(&self) -> Result<u32>
pub fn get_array_length(&self) -> Result<u32>
Perform is_array
check before get the length
if Object
is not array, ArrayExpected
error returned
sourcepub fn get_array_length_unchecked(&self) -> Result<u32>
pub fn get_array_length_unchecked(&self) -> Result<u32>
use this API if you can ensure this Object
is Array
