Rollup merge of #140848 - kornelski:not-a-dead-end, r=compiler-errors

Improved error message for top-level or-patterns

I was confused by "top-level or-patterns are not allowed in `let` bindings" error, because it sounded like or-patterns were completely unsupported.

This error has an auto-fix suggestion that shows otherwise, but the auto-fix isn't always visible in IDEs.

I've changed the wording to be consistent with "`Fn` bounds require arguments in parentheses", and it doesn't sound like a dead-end any more.

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).
