Function titanium::desktop::gui::libdruid::piet::cairo::glib::subclass::register_interface

pub fn register_interface<T>() -> Typewhere
    T: ObjectInterface,

Register a glib::Type ID for T.

This must be called only once and will panic on a second call.

The object_interface! macro will create a type_() function around this, which will ensure that it’s only ever called once.
