It became unnecessary since a06baa5 reformatted the file.
This function has a variable `changed` that is erroneously used for two related-but-different purpose: - to detect if the current element has changed; - to detect if any elements have changed. As a result, its use for the first purpose is broken, because if any prior element changed then the code always thinks the current element has changed. This is only a performance bug, not a correctness bug, because we frequently end up calling `assign_unpacked` unnecessarily to overwrite the element with itself. This commit adds `any_changed` to correctly distinguish between the two purposes. This is a small perf win for some benchmarks.
This is a small perf win.

Strip unnecessary subexpression It became unnecessary since a06baa5 reformatted the file. The comment is currently a bit misleading.
…, r=nikomatsakis Improve `merge_from_succ` A couple of small performance wins. r? @nikomatsakis
… r=oli-obk Make more arithmetic functions unstably const This is a smaller version of rust-lang#66884 (thanks @9999years) that constifies many of the arithmetic functions on integer primitives from rust-lang#53718 that were blocked on rust-lang#49146. This makes the following things unstably const. - `feature = const_int_unchecked_arith` - `intrinsics::unchecked_add` - `intrinsics::unchecked_sub` - `intrinsics::unchecked_mul` - `intrinsics::unchecked_div` - `intrinsics::unchecked_rem` - `feature = const_checked_int_methods` - `checked_add` - `checked_sub` - `checked_mul` - `checked_div` (Uses `intrinsics::unchecked_div` internally) - `checked_rem` (Uses `intrinsics::unchecked_rem` internally) - `checked_neg` - `checked_shl` - `checked_shr` - `checked_abs` - `feature = const_saturating_int_methods` - `saturating_mul` - `saturating_neg` (Uses `intrinsics::unchecked_sub` internally) - `saturating_abs` (Uses `intrinsics::unchecked_sub` internally) - `feature = const_wrapping_int_methods` - `wrapping_div` - `wrapping_rem` - `feature = const_overflowing_int_methods` - `overflowing_div` - `overflowing_rem` - `feature = const_euclidean_int_methods` - `checked_div_euclid` - `checked_rem_euclid` - `wrapping_div_euclid` - `wrapping_rem_euclid` - `overflowing_div_euclid` - `overflowing_rem_euclid` Exponentiation and operations on the `NonZero` types are left to a later PR. r? @oli-obk cc @rust-lang/wg-const-eval @rust-lang/libs
…, r=estebank Clean up E0264, E0267 and E0268 explanations r? @Dylan-DPC
On suggesting `#![recursion_limit = "X"]`, note current crate name This would have saved me much confusion e.g. when reading the log output in rust-lang#68788 (comment). r? @estebank
doc fix on doc attribute None
Fix issue number of `capacity` method Follow-up of rust-lang#68558 (comment) r? @alexcrichton
…=michaelwoerister Merge item id stable hashing functions Supersedes rust-lang#67999 splitting out the pure cleanup bits, i.e. merging `hash_item_id`, `hash_impl_item_id` and `hash_trait_item_id` into a common `hash_reference_to_item`. r? @michaelwoerister
