This is to provide a more explicit statement against a code pattern that many people end up coming with, since the reason of it being unsound comes from the badly known single-allocation validity rule. Providing that very pattern as a counter-example could help mitigate that. Co-authored-by: Ralf Jung <[email protected]>
Intern predicates Implements the first step of rust-lang/compiler-team#285 Renames `ty::Predicate` to `ty::PredicateKind`, which is now interned. To ease the transition, `ty::Predicate` is now a struct containing a reference to `ty::PredicateKind`. r? @ghost

This PR caused a rather large perf regression. Looking at the per-query results, the slowdown is in trait solving, so it is most likely #72055. There's one other candidate PR, #71718, whose perf run is not yet complete, but it is unlikely to have caused the regression. |

Probably the best way to measure this is to submit a PR that reverts the suspect, and perf-test that. |
