Hello
I don’t know why you don’t want to implement heritage of classes but it will be easier if will be a macro like: implement_trait_on_object(trait, self.c, except_methods)!
for example:
pub struct Widget {
c: gtk::Box
}
impl BoxExt for Widget {
implement_trait_on_object(BoxExt, self.c, ['get_homogeneous'])!
fn get_homogeneous(&self) -> bool {
self.c.get_homogeneous()
}
}
Rust complain about missing 1 parameter but it not display what the missing parameter. In the trait there is only one parameter.
It better if rust display the function header that needed.
error[E0049]: method `set_center_widget` has 1 type parameter but its trait declaration has 2 type parameters
--> src/widget.rs:63:25

63 | fn set_center_widget<P: IsA<gtk::Widget>>(&self, widget: Option<&P>)
| ^^^^^^^^^^^^^^^^^^^^^ found 1 type parameter, expected 2
