Add ADT variant infomation to StableMIR and finish implementing TyKind::internal() Introduce a `VariantDef` type and a mechanism to retrieve the definition from an `AdtDef`. The `VariantDef` representation itself is just a combination of `AdtDef` and `VariantIdx`, which allow us to retrieve further information of a variant. I don't think we need to cache extra information for now, and we can translate on an on demand manner. I am leaving the fields public today due to https://github.com/rust-lang/project-stable-mir/issues/56, but they shouldn't. For this PR, I've only added a method to retrieve the variant name, and its fields. I also added an implementation of `RustcInternal` that allow users to retrieve more information using Rust internal APIs. I have also finished the implementation of `RustcInternal` for `TyKind` which fixes https://github.com/rust-lang/project-stable-mir/issues/46. ## Motivation Both of these changes are needed in order to properly interpret things like projections. For example, - The variant definition is used to find out which variant we are downcasting to. - Being able to create `Ty` from `TyKind` helps for example processing each stage of a projection, like the code in `place.ty()`. |
