 GStreamer is based on the GLib object system ([GObject](https://developer.gnome.org/gobject/stable/)). C (just like Rust) does not have built-in support for object orientated programming, inheritance, virtual methods and related concepts, and GObject makes these features available in C as a library. Without language support this is a quite verbose endeavour in C, and the `glib` crate tries to expose all this in a (as much as possible) Rust-style API while hiding all the details that do not really matter.
