fn new_instance( js_env: &JsEnv, js_args: Vec<*mut napi_value__> ) -> Result<*mut napi_value__, NjError>

new instance

fn unwrap_mut( js_env: &JsEnv, instance: *mut napi_value__ ) -> Result<&'static mut Self, NjError>

given instance, return my object

fn unwrap( js_env: &JsEnv, instance: *mut napi_value__ ) -> Result<&'static Self, NjError>

fn properties() -> PropertiesBuilder

fn js_init(js_exports: &mut JsExports) -> Result<(), NjError>

define class and properties under exports

extern "C" fn js_new( env: *mut napi_env__, info: *mut napi_callback_info__ ) -> *mut napi_value__

call when Javascript class constructor is called For example: new Car(…)

extern "C" fn js_finalize( _env: *mut napi_env__, finalize_data: *mut c_void, _finalize_hint: *mut c_void )
