mgca: Lower all const paths as `ConstArgKind::Path` When `#![feature(min_generic_const_args)]` is enabled, we now lower all const paths in generic arg position to `hir::ConstArgKind::Path`. We then lower assoc const paths to `ty::ConstKind::Unevaluated` since we can no longer use the anon const expression lowering machinery. In the process of implementing this, I factored out `hir_ty_lowering` code that is now shared between lowering assoc types and assoc consts. This PR also introduces a `#[type_const]` attribute for trait assoc consts that are allowed as const args. However, we still need to implement code to check that assoc const definitions satisfy `#[type_const]` if present (basically is it a const path or a monomorphic anon const). 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).
