Rollup merge of #133136 - ChayimFriedman2:get-many-mut, r=Amanieu

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.

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).

Quick Start
