### Unresolved Questions
<!--
Include any open questions that need to be answered before the feature can be
stabilised.
-->

 - [x] ~`impl Div for Saturating<T>` falls back on inner integer division - which seems alright?~
    - [x] add `saturating_div`? (to respect division by `-1`)
 - [x] There is no `::saturating_shl` and `::saturating_shr`. (How to) implement `Shl`, `ShlAssign`, `Shr` and `ShrAssign`?
   - [naively](3f7d2ce28f)
 - [x] ~`saturating_neg` is only implemented on [signed integer types](https://doc.rust-lang.org/std/?search=saturating_n)~
 - [x] Is the implementation copied over from the `Wrapping`-type correct for `Saturating`?
   - [x] `Saturating::rotate_left`
   - [x] `Saturating::rotate_right`
   - [x] `Not`
   - [x] `BitXorOr` and `BitXorOrAssign`
   - [x] `BitOr` and `BitOrAssign`
   - [x] `BitAnd` and `BitAndAssign`
   - [x] `Saturating::swap_bytes`
   - [x] `Saturating::reverse_bits`
