Trait IsA 

pub unsafe trait IsA<T>:
    ObjectType
    + Into<T>
    + AsRef<T>
    + Borrow<T>
where
    T: ObjectType,
{ }

Declares the “is a” relationship.

Self is said to implement T.

For instance, since originally GtkWidget is a subclass of GObject and implements the GtkBuildable interface, gtk::Widget implements IsA<glib::Object> and IsA<gtk::Buildable>.

The trait can only be implemented if the appropriate ToGlibPtr implementations exist.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
