Improve the ICE message for invalid nullary intrinsic calls In https://github.com/rust-lang/rust/issues/148104, we found the panic message here rather confusing, and (if I'm reading the tea leaves right) that's because the intended audience for either side of the phrase is very different. I think this is more clear if/when this is encountered by users. I expect this ICE to be hit in practice by people calling the `size_of` and `align_of` intrinsics, so it's now _kind of_ helpful for those users too. The original effort to stop backends from needing to support nullary intrinsics added a note to all these const-only intrinsics, but when https://github.com/rust-lang/rust/pull/147793 ported two more the paragraph wasn't added. I've added it. |

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).
