bors 698fcc8219 Auto merge of #117517 - klinvill:smir-projections, r=ouz-a ... Add richer structure for Stable MIR Projections Resolves https://github.com/rust-lang/project-stable-mir/issues/49. Projections in Stable MIR are currently just strings. This PR replaces that representation with a richer structure, namely projections become vectors of `ProjectionElem`s, just as in MIR. The `ProjectionElem` enum is heavily based off of the MIR `ProjectionElem`. This PR is a draft since there are several outstanding issues to resolve, including: - How should `UserTypeProjection`s be represented in Stable MIR? In MIR, the projections are just a vector of `ProjectionElem<(),()>`, meaning `ProjectionElem`s that don't have Local or Type arguments (for `Index`, `Field`, etc. objects). Should `UserTypeProjection`s be represented this way in Stable MIR as well? Or is there a more user-friendly representation that wouldn't drag along all the `ProjectionElem` variants that presumably can't appear? - What is the expected behavior of a `Place`'s `ty` function? Should it resolve down the chain of projections so that something like `*_1.f` would return the type referenced by field `f`? - Tests should be added for `UserTypeProjection`		2023-11-15 06:05:54 +00:00
