rustCreating pointer from specific address in Rust

In Rust, you can create a pointer from a specific address using the std::ptr::NonNull type. This type is a wrapper around a raw pointer that ensures that the pointer is not null. To create a pointer from a specific address, you can use the new_unchecked method, which takes a raw pointer and returns a NonNull instance. For example, to create a pointer from the address 0x12345678, you can use the following code:

let ptr = std::ptr::NonNull::new_unchecked(0x12345678 as *mut i32);

The new_unchecked method does not perform any checks on the pointer, so it is important to make sure that the pointer is valid before using it. If the pointer is invalid, it can lead to undefined behavior.
