I have been trying to read:

https://people.gnome.org/~federico/blog/how-glib-rs-works-part-1.html

and the following two pieces (it seems there were going to be more but they
didn't appear) to try and understand the Rust GLib stuff, but I have to admit,
I am failing so far, hence the earlier email. I shall persist though as I want
to know this stuff.

I am guessing that one has to read the C API documents to determine whether to
use "none" or "full" for the functions of the API in Rust. However the current
problem is dealing with data structures directly so I am guessing use "none".
In C/C++ it was a question of using the gst_date_time_ref function, I am
assuming this is effectively what happens when using from_glib_none?
