HashMap::get_many_mut on stable

Is there a simple way to steal this one function HashMap in std::collections - Rust to use on stable, without having to use Rust nightly ?

I know the common trick is to store a HashMap<K, RefCell<V>> where you can then take multiple read-only refs, and run .borrow() on them, but I am curious if there is a way to just steal this one function instead.

Thanks!

If it's feasible, just use hashbrown as a drop-in replacement for std HashMap.

For the exact question: No, there's not. You can create an extension trait with get_many_mut with an implementation that does not use internal details, but that's as far as you can get.
