This pull request partially reverts changes from e16c3b4a4421 Original motivation for this assert was described with "A WorkProduct without a saved file is useless" which was true at the time but now it is possible to have work products with other types of files (llvm-ir, asm, etc) and there are bugreports for this failure: For example: https://github.com/rust-lang/rust/issues/123695 Fixes https://github.com/rust-lang/rust/issues/123234 Now existing `assert` and `.unwrap_or_else` are unified into a single check that emits slightly more user friendly error message if an object files was meant to be produced but it's missing
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).
