Module data

Data types that are meant to be shared and read across Duat.

The data types revolve around the RwLock struct from parking_lot, and are adapters that may block the mutation of the inner data, for the purpose of making it available for reading to any extension on Duat.

The first data type is RwData, which is a read and write wrapper over information. It should mostly not be shared, being used instead to write information while making sure that no other part of the code is still reading it. The second data type is RoData, or read only data. It is derived from the first one, and cannot mutate the inner data.

This type is used internally in order to keep track of state, like widgets, input methods, etc.

One of the main external uses for this macro is in creating automatically update StatusLine fields.
