Stabilize `const_slice_split_at_mut` and `const_slice_first_last_chunk` Stabilizes #101804 and the remainder of #111774. FCP proposed in the tracking issue. Requires #130403 (or it would need a rustc_allow_const_fn_unstable for it) Stabilized const API: ```rust // slice impl [T] { pub const fn split_at_mut(&mut self, mid: usize) -> (&mut [T], &mut [T]); pub const fn split_at_mut_unchecked(&mut self, mid: usize) -> (&mut [T], &mut [T]); pub const fn split_at_mut_checked(&mut self, mid: usize) -> Option<(&mut [T], &mut [T])>; pub const fn first_chunk_mut<const N: usize>(&mut self) -> Option<&mut [T; N]>; pub const fn last_chunk_mut<const N: usize>(&mut self) -> Option<&mut [T; N]>; pub const fn split_first_chunk_mut<const N: usize>(&mut self) -> Option<(&mut [T; N], &mut [T])>; pub const fn split_last_chunk_mut<const N: usize>(&mut self) -> Option<(&mut [T; N], &mut [T])>; } ``` Closes #101804 Closes #111774 cc `@RalfJung` |

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).
