Serializers
===========
The library implements the JSON serializers for all available Google Calendar objects. JSON format is as specified in
the `official API documentation`_. In general, you won't need to use them, ``gcsa`` serializes everything as needed
under the hood. It is documented just so you know they exist and can be used if necessary.
.. note::
Note that serializers' ``to_json`` methods ignore read-only fields of the objects.
Read-only fields of the objects are ones that are passed to the parameters of their ``__init__`` with
underscores, e.g. ``Event(_updated=25/Nov/2020)``.
