`rustc_codegen_llvm` relied on `Deref` impls where `Deref::Target` was or contained an extern type - in my experimental implementation of rust-lang/rfcs#3729, this isn't possible as the `Target` associated type's `?Sized` bound cannot be relaxed backwards compatibly (unless we come up with some way of doing this). In later pull requests with the rust-lang/rfcs#3729 implementation, breakage like this could only occur for nightly users relying on the `extern_types` feature. Upstreaming this to avoid needing to keep carrying this patch locally, and I think it'll necessarily need to change eventually. |

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).
