 - hash: add a function to look up hash algo structs
 - rust: add a hash algorithm abstraction
 - rust: add a ObjectID struct
 - hash: use uint32_t for object_id algorithm
 - conversion: don't crash when no destination algo
 - repository: require Rust support for interoperability

 The code to maintain mapping between object names in multiple hash
 functions is being added, written in Rust.

 Any progress on CI breakages???

I just sent v3 yesterday which fixes the CI breakages.

Yup, I replaced the topic with the latest one, and the draft for the
next issue of "What's cooking" has this entry updated already.

Thanks.

 Comments?  v1 saw a lot of discussions, v2 didn't, and this is v3,
 which is essentially identical to v2 with CI fixes (which work!).
