To be more specific, Rust does have among other things: std::ptr::null() - an actual null pointer, probably the zero address on your hardware, and this isn't even an unsafe function. On the other hand, you won't find many uses for a null pointer so, I mean, congrats on obtaining one and good luck with that. std::ptr::null_mut() - a mutable null pointer, similarly unlikely to be of any use to you in safe Rust, but also not an unsafe thing to ask for. But, these are pointers, so they're not values that say, a String could take, or a Vec<String> or whatever, only actual raw pointers can be null.
