[src]
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<()>
[src]
This method allows the efficient definition of multiple properties on a given object.
pub fn get_array_length(&self) -> Result<u32>
[src]
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>
[src]
use this API if you can ensure this Object
is Array
