Stabilize `const_atomic_from_ptr` The API is already stable since https://github.com/rust-lang/rust/pull/115719, but const stability was blocked on `const_mut_refs`. Since that was recently stabilized, const stabilize the following: ```rust // core::atomic impl AtomicBool { pub const unsafe fn from_ptr<'a>(ptr: *mut bool) -> &'a AtomicBool; } impl<T> AtomicPtr<T> { pub const unsafe fn from_ptr<'a>(ptr: *mut *mut T) -> &'a AtomicPtr<T>; } impl AtomicU8 { pub const unsafe fn from_ptr<'a>(ptr: *mut u8) -> &'a AtomicU8; } impl AtomicU16 { pub const unsafe fn from_ptr<'a>(ptr: *mut u16) -> &'a AtomicU16; } impl AtomicU32 { pub const unsafe fn from_ptr<'a>(ptr: *mut u32) -> &'a AtomicU32; } impl AtomicU64 { pub const unsafe fn from_ptr<'a>(ptr: *mut u64) -> &'a AtomicU64; } impl AtomicUsize { pub const unsafe fn from_ptr<'a>(ptr: *mut usize) -> &'a AtomicUsize; } impl AtomicI8 { pub const unsafe fn from_ptr<'a>(ptr: *mut i8) -> &'a AtomicI8; } impl AtomicI16 { pub const unsafe fn from_ptr<'a>(ptr: *mut i16) -> &'a AtomicI16; } impl AtomicI32 { pub const unsafe fn from_ptr<'a>(ptr: *mut i32) -> &'a AtomicI32; } impl AtomicI64 { pub const unsafe fn from_ptr<'a>(ptr: *mut i64) -> &'a AtomicI64; } impl AtomicIsize { pub const unsafe fn from_ptr<'a>(ptr: *mut isize) -> &'a AtomicIsize; } ``` |

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).
