Hi! Thanks for this.

I find that documentation completely insufficient to implement a virtual WAL. The example (which I had looked into) it's just a "do nothing" wrapper. I learn that there are 25 methods I should implement, and that I can just forward them to another implementation.

For my bindings, I implemented an entire SQLite VFS from scratch for a handful of different platforms, including file-locking and shared-memory primitives. However, and having studied your virtual WAL code for about a month, I still have no idea where to even start. It just doesn't feel like an coherent API (more like an internal SQLite API, simply exposed for outside use).

I'll look into Bottomless, but I'm not very hopeful at this point. Maybe it's just me and Rust; if that is so, I'm sorry.
