Or "supertypes" as they are called in salsa-rs#578. They are of the form: ``` enum Enum { Input(Input), Interned(Interned), ... } ```
We were storing the type information, 3 words wide, for each memo in each slot, while it is always constant wrt. the ingredient (different slots of the same ingredients will always have the same memos in the same order). This introduces some more unsafety, and the result wasn't as fast so I also had to use some lock-free structures, but the result is worth it: this shaves off 230mb from rust-analyzer with new Salsa.
✅ Deploy Preview for salsa-rs canceled.
