Trait gstreamer::prelude::IsA[][src]

pub unsafe trait IsA<T>: Wrapper + UnsafeFrom<ObjectRef> + ToGlibPtr<'a, *mut <T as Wrapper>::GlibType> + StaticType + Into<ObjectRef> where
    T: Wrapper + UnsafeFrom<ObjectRef> + StaticType
{ }

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.

T always implements IsA<T>.
