Signature

def _find_my_config ( self , cfg : Config ) → t.Any

extract my config from a global Config object

will construct a Config object of only the config values that apply to me based on my mro(), as well as those of my parent(s) if they exist.

If I am Bar and my parent is Foo, and their parent is Tim, this will return merge following config sections, in this order

[Bar, Foo.Bar, Tim.Foo.Bar]

With the last item being the highest priority.
