How to create a static mutable hashmap?

Question

How to create a static mutable hash? I'm fine with unsafe code.

Normal static does not allow global variables with constructors.

As an example, I want to have https://gist.github.com/Kimundi/8782487 , but the HASHMAP can be changed.

I understand that a global shared mutable state is not that very rusty, but I just want to know if this is possible.
