check `mut`-restriction when tuple constructor is used as a value * check mut restriction when tuple ctor is used as a value * add missing stderr file for mut-restriction ctor value test * simplify def_kind matching in tuple ctor mut restriction check Match the DefKind::Ctor directly on the result of tcx.def_kind instead of binding it to a local first. Extend the ctor-value ui test with additional enum variants covering plain and crate-restricted fields. * test: exercise new ctor variants * address review: drop shell.nix, add tests

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
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).
