Description
Feature gate: #![feature(const_split_off_first_last)]
This is a tracking issue for using <[T]>::split_off_* functions in const. These functions remove either the first or last element from a slice and return a reference or mutable reference to that element.
The original functions were stabilized with the slice_take feature.slice_take tracking issue: #62280
Public API
impl [T] { pub const fn split_off_first<'a>(self: &mut &'a Self) -> Option<&'a T>; pub const fn split_off_first_mut<'a>(self: &mut &'a mut Self) -> Option<&'a mut T>; pub const fn split_off_last<'a>(self: &mut &'a Self) -> Option<&'a T>; pub const fn split_off_last_mut<'a>(self: &mut &'a mut Self) -> Option<&'a mut T>; }
