Remove `MaybeUninit::uninit_array()` and replace it with inline const blocks. \[This PR originally contained the changes in #125995 too. See edit history for the original PR description.] The documentation of `MaybeUninit::uninit_array()` says: > Note: in a future Rust version this method may become unnecessary when Rust allows [inline const expressions](https://github.com/rust-lang/rust/issues/76001). The example below could then use `let mut buf = [const { MaybeUninit::<u8>::uninit() }; 32];`. The PR adding it also said: <https://github.com/rust-lang/rust/pull/65580#issuecomment-544200681> > if it’s stabilized soon enough maybe it’s not worth having a standard library method that will be replaceable with `let buffer = [MaybeUninit::<T>::uninit(); $N];` That time has come to pass — inline const expressions are stable — so `MaybeUninit::uninit_array()` is now unnecessary. The only remaining question is whether it is an important enough *convenience* to keep it around. I believe it is net good to remove this function, on the principle that it is better to compose two orthogonal features (`MaybeUninit` and array construction) than to have a specific function for the specific combination, now that that is possible. |
