Return the user data previously attached to self
with the given key
, if any,
without incrementing the reference count.
The pointer is valid when it is returned from this method,
until the cairo object that self
represents is destroyed
or remove_user_data
or set_user_data
is called with the same key.

) -> Result<(), Error>
Unattached from self
the user data associated with key
, if any.
If there is no other Rc
strong reference, the data is destroyed.
