Partially stabilize `feature(new_uninit)` Finished comment period: https://github.com/rust-lang/rust/issues/63291#issuecomment-2183022955 The following API has been stabilized from https://github.com/rust-lang/rust/issues/63291 ```rust impl<T> Box<T> { pub fn new_uninit() -> Box<MaybeUninit<T>> {…} } impl<T> Rc<T> { pub fn new_uninit() -> Rc<MaybeUninit<T>> {…} } impl<T> Arc<T> { pub fn new_uninit() -> Arc<MaybeUninit<T>> {…} } impl<T> Box<[T]> { pub fn new_uninit_slice(len: usize) -> Box<[MaybeUninit<T>]> {…} } impl<T> Rc<[T]> { pub fn new_uninit_slice(len: usize) -> Rc<[MaybeUninit<T>]> {…} } impl<T> Arc<[T]> { pub fn new_uninit_slice(len: usize) -> Arc<[MaybeUninit<T>]> {…} } impl<T> Box<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Box<T> {…} } impl<T> Box<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Box<[T]> {…} } impl<T> Rc<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Rc<T> {…} } impl<T> Rc<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Rc<[T]> {…} } impl<T> Arc<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Arc<T> {…} } impl<T> Arc<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Arc<[T]> {…} } ``` The remaining API is split between new issues - `new_zeroed_alloc`: https://github.com/rust-lang/rust/issues/129396 - `box_uninit_write`: https://github.com/rust-lang/rust/issues/129397 All relevant code is thus either stabilized or split out of that issue, so this closes #63291 as, with the FCP concluded, that issue has served its purpose. try-job: x86_64-rust-for-linux

Rust
//! The "main crate" of the Rust compiler. This crate contains common
|
|
//! type definitions that are used by the other crates in the rustc
|
|
//! "family". Some prominent examples (note that each of these modules
|
|
//! has their own README with further details).
|
|
//!
|
|
//! - **HIR.** The "high-level (H) intermediate representation (IR)" is
|
|
//! defined in the [`hir`] module.
|
|
//! - **MIR.** The "mid-level (M) intermediate representation (IR)" is
|
|
//! defined in the [`mir`] module. This module contains only the
|
|
//! *definition* of the MIR; the passes that transform and operate
|
|
//! on MIR are found in `rustc_const_eval` crate.
|
|
//! - **Types.** The internal representation of types used in rustc is
|
|
//! defined in the [`ty`] module. This includes the
|
|
//! [**type context**][ty::TyCtxt] (or `tcx`), which is the central
|
|
//! context during most of compilation, containing the interners and
|
|
//! other things.
|
|
//!
|
|
//! For more information about how rustc works, see the [rustc dev guide].
|

|
|
//! # Note
|
|
//!
|
|
//! This API is completely unstable and subject to change.
