Description
The feature gate for the issue is #![feature(array_chunks)]
.
Also tracks as_(r)chunks(_mut)
in #![feature(slice_as_chunks)]
-- these were FCPed starting at #74985 (comment) below.
About tracking issues
Tracking issues are used to record the overall progress of implementation.
They are also uses as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.
Steps
RestrictMakeN
to values greater than 0 at compile time instead of using a runtime panic.<[T]>::array_*
methods fail to compile on 0 len arrays #99471Support calls whereN == 0
is unreachable due to conditionals Tracking Issue for slice::array_chunks #74985 (comment)- It was decided that a runtime panic is appropriate: Tracking Issue for slice::array_chunks #74985 (comment)

Unresolved Questions
- Iterator vs slices, Does
[T]::array_chunks
really need to be an iterator? #76354

Is there any intention of providing the reverse versions of these functions?
