Instantiate QObject 'based' struct in Rust code

[uafcybs]

Hello,
Is there a way to create an instance of QObject 'based' struct in the Rust code (in order to set to QML context)?

use qmetaobject::*;

#[allow(non_snake_case)]
#[derive(Default, QObject)]
pub struct ItemsModel {
    base: qt_base_class!(trait QObject),
    itemRect: qt_method!(fn(&mut self, index: usize) -> qmetaobject::QRectF),
}

impl ItemsModel {
    #[allow(non_snake_case)]
    fn itemRect(&mut self, index: usize) -> qmetaobject::QRectF {
        qmetaobject::QRectF{ x:0.0, y:0.0, width:0.0, height:0.0 }
    }
    pub fn new() -> Self {
        Self{ base: ??? , itemRect: ??? } 
    }
}

// ...
fn main() {
    //...
    let mut engine = QmlEngine::new();
    let rc = RefCell::new(ItemsModel::new());
    let model = qmetaobject::QObjectPinned::new(&rc);
    engine.set_object(model);
    engine.load_file("qrc:/udraw/qml/main.qml".into());
    engine.exec();
}

I'm not good at Rust yet and just trying to port my C++/QML project.

Thanks in advance

i think you can try with something like
Self { base: Default::default(), itemRect: Default::default() }
