`windows-bindgen` needs documentation
Motivation
It’s close to impossible to use windows-bindgen without documentation.
Drawbacks
None
Rationale and alternatives
The Gen class has mysterious fields with cryptic names which say nothing about what are those, how and why they should be used etc.
Additional context
No response
Its early days but yes docs for the bindgen crate are needed as I expect developers to eventually use this crate directly.
The windows-bindgen crate is now dramatically simpler than it was back when this issue was opened. It now also has some rudimentary function comments. Hopefully, that suffices for the time being. I still have a lot planned for bindgen and metadata, but it's pretty functional and straightforward today so I'll close this out for now.
