Stabilise `as_array` in `[_]` and `*const [_]`; stabilise `as_mut_array` in `[_]` and `*mut [_]`. Tracking issue: rust-lang/rust#133508 Closes: rust-lang/rust#133508 This PR stabilises the `as_array` and `as_mut_array` associated functions from the `core_slice_as_array` feature gate: ```rust // core::slice impl<T> [T] { pub const fn as_array<const N: usize>(&self) -> Option<&[T; N]>; pub const fn as_mut_array<const N: usize>(&mut self) -> Option<&mut [T; N]>; } // core::ptr impl<T> *const [T] { pub const fn as_array<const N: usize>(self) -> Option<*const [T; N]>; } impl<T> *mut [T] { pub const fn as_mut_array<const N: usize>(self) -> Option<*mut [T; N]>; } ``` It also updates the feature gates and tracking issues for all items associated with the previous `slice_as_array` tracking issue (including these four that are being stabilised). ~~FCP missing.~~
The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
