Hi @Mathys-Gasnier,

I’ve updated the snippets to match the new format and resolved the merge conflicts. Can you take a look and let me know if everything’s good or if there’s anything else I should fix? Thanks!

Hey, thanks for updating your snippets, but looking at your PR, it still seems to modify /public/consolidated/all_snippets.json which is a file that doesn't exists, the same goes for /public/data/rust.json
