This has become even more of a challenge since we plan to make
it a @safe @nogc poster child.
If anyone wants to help with this project please contact me.
At the moment reworked @safe @nogc database drivers would be
most helpful.
I'll soon publish a small RC, Uniq, Weak library.
Unbuffered IO foundations are already here
https://github.com/MartinNowak/io, but not yet practically
proven, and still lacking vibe-core scheduler/eventcore
integration.
If someone wants to see this happen, but doesn't have enough time
to contribute,
you could help to crowdfund this work, so I could afford to spent
more time working on this.
Get in contact with us for more details.
