Are there any tutorials you would like to have made?

I've been finding it difficult to find good tutorials on different topics within Rust, so I've had to learn what to do the hard way. I don't want this hard-won knowledge to got waste, so I am considering making tutorials based on my experience. If you guys have any requests for a specific tutorial, let me know. I would also like to mention that this would be an in-my-free-time venture, so I'll do my best, but I still have life stuff to which I need to attend. Thanks in advance.
