stabilize const_intrinsic_copy Fixes https://github.com/rust-lang/rust/issues/80697 This stabilizes ```rust mod ptr { pub const unsafe fn copy_nonoverlapping<T>(src: *const T, dst: *mut T, count: usize); pub const unsafe fn copy<T>(src: *const T, dst: *mut T, count: usize); } impl *const T { pub const unsafe fn copy_to(self, dest: *mut T, count: usize); pub const unsafe fn copy_to_nonoverlapping(self, dest: *mut T, count: usize); } impl *mut T { pub const unsafe fn copy_to(self, dest: *mut T, count: usize); pub const unsafe fn copy_to_nonoverlapping(self, dest: *mut T, count: usize); pub const unsafe fn copy_from(self, src: *const T, count: usize); pub const unsafe fn copy_from_nonoverlapping(self, src: *const T, count: usize); } impl <T> NonNull<T> { pub const unsafe fn copy_to(self, dest: NonNull<T>, count: usize); pub const unsafe fn copy_to_nonoverlapping(self, dest: NonNull<T>, count: usize); pub const unsafe fn copy_from(self, src: NonNull<T>, count: usize); pub const unsafe fn copy_from_nonoverlapping(self, src: NonNull<T>, count: usize); } ``` In particular, this reverts https://github.com/rust-lang/rust/pull/117905, which reverted https://github.com/rust-lang/rust/pull/97276. The `NonNull` methods are not listed in the tracking issue, they were added to this feature gate in https://github.com/rust-lang/rust/pull/124498. The existing [FCP](https://github.com/rust-lang/rust/issues/80697#issuecomment-1022585839) does not cover them. They are however entirely identical to the `*mut` methods and already stable outside `const`. ``@rust-lang/libs-api`` please let me know if FCP will be required for the `NonNull` methods. |

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).
