In all our examples, we have used standard library threads. As we have discussed, these threads have their own stack, so if we want to use variables that we created in the main thread we will need to send them to the thread. This means that we will need to use things such as Arc to share non-mutable data. Not only that, having their own stack means that they will also consume more memory and eventually make the system slower if they use too much.
Crossbeam gives us some special threads that allow sharing stacks between them. They are called scoped threads. Using them is pretty simple and the crate documentation explains them perfectly; you will just need to create a Scope by calling crossbeam::scope(). You will need to pass ...
