Remove redundant lifetime bound from `impl Borrow for Cow` The lifetime bound `B::Owned: 'a` is redundant and doesn't make a difference, because `Cow<'a, B>` comes with an implicit `B: 'a`, and associated types will outlive lifetimes outlived by the `Self` type (and all the trait's generic parameters, of which there are none in this case), so the implicit `B: 'a` implies `B::Owned: 'a` anyway. The explicit lifetime bound here does however [end up in documentation](https://doc.rust-lang.org/std/borrow/enum.Cow.html#impl-Borrow%3CB%3E), and that's confusing in my opinion, so let's remove it ^^ _(Documentation right now, compare to `AsRef`, too:)_ ![Screenshot_20220722_014055](https://user-images.githubusercontent.com/3986214/180332665-424d0c05-afb3-40d8-a330-a57a2c9a494b.png) |
