Re: [MirageOS-devel] Irmin on BLOCK

[Thomas Leonard <talex5@xxxxxxxxx>]

Hi Rupert,

The main thing is to implement Irmin's AO signature:

https://github.com/mirage/irmin/blob/4ccccb5d3117e4cc1ecff4a83cc508da59006423/lib/irmin.mli#L360

i.e. given a block of data, write it to disk and return its hash.
Given a hash, return the file data.

You could write the data sequentially to the disk and keep an index of
where everything has been stored. Or, you could perhaps use the file's
hash to decide where to store it. There's also irmin-chunk
(https://github.com/mirage/irmin-chunk) which says it might help with
raw device backends, although I'm not sure what the idea is there.
