Tracking Issue for `feature(const_slice_split_at_mut)` · Issue #101804 · rust-lang/rust · GitHub

Feature gate: #![feature(const_slice_split_at_mut)]

This is a tracking issue for spliting mutable slices in const context.

// slice
pub const fn split_at_mut(&mut self, mid: usize) -> (&mut [T], &mut [T]);
pub const fn split_at_mut_unchecked(&mut self, mid: usize) -> (&mut [T], &mut [T]);
pub const fn split_at_mut_checked(&mut self, mid: usize) -> Option<(&mut [T], &mut [T])>;

• Implementation: Constify slice.split_at_mut(_unchecked) #101800
• Stabilize split_at_checked #124678
• Wait for Tracking issue for &mut T in const contexts (const_mut_refs) #57349 to be stabilized.
• Wait for Stabilize const_slice_from_raw_parts_mut #130403 since from_raw_parts_mut is used internally
• Final comment period (FCP)¹
• Stabilization PR Stabilize const_slice_split_at_mut and const_slice_first_last_chunk #130428

• None yet.
