Support ranges in `<[T]>::get_many_mut()` As per T-libs-api decision in #104642. I implemented that with a separate trait and not within `SliceIndex`, because doing that via `SliceIndex` requires adding support for range types that are (almost) always overlapping e.g. `RangeFrom`, and also adding fake support code for `impl SliceIndex<str>`. An inconvenience that I ran into was that slice indexing takes the index by value, but I only have it by reference. I could change slice indexing to take by ref, but this is pretty much the hottest code ever so I'm afraid to touch it. Instead I added a requirement for `Clone` (which all index types implement anyway) and cloned. This is an internal requirement the user won't see and the clone should always be optimized away. I also implemented `Clone`, `PartialEq` and `Eq` for the error type, since I noticed it does not do that when writing the tests and other errors in std seem to implement them. I didn't implement `Copy` because maybe we will want to put something non-`Copy` there. |
