Thanks for the feedback! I’ve reviewed the structure of other implementations in the repository. I’ll restructure and update the PR soon. Let me know if there are any specific guidelines I should follow!

You haven't matched the format of other block cipher crates. At the very least you have to implement the cipher traits. The docs folder is also not necessary a link to the HIGHT paper in crate docs will be sufficient.

You also need to add a CI config for the crate and add it to the workspace (see the root Cargo.toml).
