"Rust's compiler prevents common bugs" So does skill. No offense to you, but, this trope is getting so tiresome. If you like the language then go ahead and use it. What is it with the rust crowd that they have to come acrosslike people trying to convert your religion at your front door?
Your first point is not true. There are valid uses of memory sharing that rust will reject.
Curious what you are talking about. Multi-threaded sharing of memory for example is also easy with rust, it just doesn't let you wrote and read at the same time, and so on.
Off the top of my head, single-threaded writing to the same memory from different fields of a struct. Not to mention self-referencing like if you want to hold a buffer and have different views into it in the same structure.
Classic example: A linked list
... are entirely possible, even if rarely the right choice.
With unsafe, but how can you write a double linked list in safe rust? (without indices)
