Speed of Rust vs. C

The simplest (and often best) option is to use the Arc<Mutex<MyStruct>> pattern.

The Arc is an async reference counter that allows multiple ownership. And the nested Mutex enforces only one mutable borrow at a time.

I think you mean that Arc is an atomic reference counter (it uses atomic cpu instructions to prevent race conditions when incrementing and decrementing the ref count)

Ah yes, sorry. I remember it in my head with "async", but you're right. :)
