Correctly change type when adding adjustments on top of `NeverToAny` I'm concerned that the check only caught the problem with `fallback = !`, because at least MIR contained `<() as PartialEq>::eq(move _5, move _7)` where `_5: ()`. I rediscovered the issue when looking at #123482's crater run. r? compiler-errors Fixes #120600
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 integrate 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).
