rustc_public: Make Id types !Send / !Sync These types are Id's to a table stored in TLS, so using them from another tread will either panic, or give wrong results. Therefor, I've added a ~~`ReferencesTls`~~`ThreadLocalIndex` marker type, which ensures types arn't `Send`/`Sync`. This is a breaking change for users of the `rustc_public` crate. ~~It also changes how `DefId` and similar are `Serialize`d. It would be possible to preserve the old behavior if that's needed, but I couldn't see any tests for these.~~ EDIT: Not anymore: https://github.com/rust-lang/rust/pull/148261#discussion_r2476111612 Zulip Discussion: https://rust-lang.zulipchat.com/#narrow/channel/320896-project-stable-mir/topic/WDYM.20.22should.20not.20.20be.20shared.20across.20threads.22/with/547374171 |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
