This is an oversight, a PR to add it is welcome. |

Random piece of feedback: https://std-dev-guide.rust-lang.org/about.html never tells the reader which repository, branches, directories, etc to interact with. |

The methods for fallible slice allocation in a given allocator were missing, which was an oversight according to rust-lang/wg-allocators#130 This PR adds them as `try_new_uninit_slice_in` and `try_new_zeroed_slice_in`. Also adds missing punctuation to the doc comments of ` try_new_uninit_slice` and `try_new_zeroed_slice`

Here we go: rust-lang/rust#127415 |

That's perfect thank you. |

Add missing try_new_uninit_slice_in and try_new_zeroed_slice_in The methods for fallible slice allocation in a given allocator were missing from `Box`, which was an oversight according to rust-lang/wg-allocators#130 This PR adds them as `try_new_uninit_slice_in` and `try_new_zeroed_slice_in`. I simply copy-pasted the implementations of `try_new_uninit_slice` and `try_new_zeroed_slice` and adusted doc comment, typings, and the allocator it uses internally. Also adds missing punctuation to the doc comments of `try_new_uninit_slice` and `try_new_zeroed_slice`. Related issue is rust-lang#32838 (Allocator traits and std::heap) *I think*. Also relevant is rust-lang#63291, but I did not add the corresponding `#[unstable]` proc macro, since `try_new_uninit_slice` and `try_new_zeroed_slice` are also not annotated with it.

Hi,
while
Boxhas bothtry_new_uninit_sliceandnew_uninit_slice_in, it lackstry_new_uninit_slice_into fallibly allocate a slice of uninitialized memory with a given allocator. Is this deliberate or an oversight? What could be a good workaround for implementing this oneself?Apologies if this is not the appropriate repo for this sort of question/feature suggestion.
Cheers,
Aljoscha
