Yes it is very easy. Please see the disk_ops type in the API.

  write: BLK.r -> BLK.t -> (unit,'t) m;
  disk_sync: unit -> (unit,'t) m;

Also the disk_to_store function, and store_to_map. So if you have a
disk_ops (or store_ops) you can get a map_ops. But really this is a
B-tree library. More work needs to be done to get an efficient KV store,
or filesystem or whatever. But yes, it is already done - I looked at the
Mirage block interface a while ago and it seems reasonable and close to
what disk_ops assumes (which isn't much).

Nice, thanks!

BTW what was confusing about the structure? Did you read the overview?


Nope, I just read your included example and went to the repository and started digging around in it; I didn't notice your "documentation" link at the bottom the README, but indeed it's there.

Thanks for your interest!

Thanks for your work and the announcement!
