Description
Checkseum is a library to provide implementation of Adler-32, CRC32 and CRC32-C in C and OCaml.
This library use the linking trick to choose between the C implementation (checkseum.c) or the OCaml implementation (checkseum.ocaml). This library is on top of optint to get the best representation of an int32.

Checkseum
Chekseum is a library which implements ADLER-32 and CRC32C Cyclic Redundancy Check. It provides 2 implementation, the first in C and the second in OCaml. The library is on top of optint
to get the best representation of the CRC in the OCaml world.
Linking trick / variant
Then, as digestif
, checkseum
uses the linking trick. So if you want to use checkseum
in a library, you can link with the checkseum
package which does not provide an implementation. Then, end-user can choose between the C implementation or the OCaml implementation (both work on Mirage).
So, in utop
, to be able to fully use checkseum
, you need to write:
$ utop -require checkseum.c
or
$ utop -require checkseum.ocaml
In a dune
workspace, the build-system is able to choose silently default implementation (checkseum.c
) for your executable if you don't specify one of them. A dune-library is not able to choose an implementatio but still able to use the virtual library checkseum
.
