error on unsized AnonConsts The constant evaluator does not support unsized types, however, unsized AnonConsts were never checked to be Sized, so no errors were generated on them and the constant was attempted to be constant evaluated. This caused the constant evaluator to ICE. Add a special case for AnonConsts in rustc_hir_typeck, as suggested by @BoxyUwU in rust-lang/rust#137582. There is no checking for `#![feature(unsized_const_params)]` which should eventually revert this check when the feature becomes more implemented. That issue is assigned to @el-ev but I started looking into this as a jumping off point / motivation to learn some compiler stuff, and I eventually got to the point of fixing it, so I'm submitting a PR anyway. So just a ping/FYI to @el-ev that I'm submitting this, sorry! There are three relevant github issues to this ICE that I could find: - fixes rust-lang/rust#137582 - fixes rust-lang/rust#151591 The similar issue rust-lang/rust#104685 is NOT fixed, it might be good to glance at that before verifying this particular fix, to make sure this fix is actually in the right place. (I haven't looked at it much) r? @BoxyUwU |

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).
