Simple63 is an OCaml module for compressing and decompressing
sequences of integers along the ideas described in the 2010 paper by
Anh and
Moffat.
Like Simple-8b technique described in that paper, Simple63 is a
word-bounded, and (as the name suggests) is the result of adapting
Simple-8b to work with OCaml's 63-bit integers. While using int64
integer types would have been possible, the additional boxing required
to manipulate int64's make this option unappealing.
Example usage:
let in_lst = [1; 22; 333; 4444] in
let in_seq = List.to_seq in_lst in
let out_seq = encode_to_seq in_seq in
(* confirm that we get out what we've put in: *)
let in_seq' = decode_from_seq out_seq in
let in_lst' = List.of_seq in_seq' in
assert (in_lst = in_lst')
