what's the normal way to do sparse arrays in rust? Vec<Option<T>>? HashMap<usize, T>?
-
I don't think there's a "normal" here, both have different performance characteristics. HashMap is overall better for most use cases I think. (OrderMap<usize, T> is yet another option)
Really? OrderMap seems like a horrible way to implement option. I didn't realize there were enough impls for it to be "yet another" one

What? I said it's an option, not a way to implement option
