bors ef55a0a92f Auto merge of #75207 - dylni:add-slice-check-range, r=KodrAus ... Add `slice::check_range` This method is useful for [`RangeBounds`] parameters. It's even been [rewritten](22ee68dc58/src/librustc_data_structures/sorted_map.rs (L214)) [many](22ee68dc58/library/alloc/src/vec.rs (L1299)) [times](22ee68dc58/library/core/src/slice/mod.rs (L2441)) in the standard library, sometimes assuming that the bounds won't be [`usize::MAX`]. For example, [`Vec::drain`] creates an empty iterator when [`usize::MAX`] is used as an inclusive end bound: ```rust assert!(vec![1].drain(..=usize::max_value()).eq(iter::empty())); ``` If this PR is merged, I'll create another to use it for those methods.
