JoJoJet f2f8f9097f Add safe constructors for untyped pointers Ptr and PtrMut (#6539) ... # Objective Currently, `Ptr` and `PtrMut` can only be constructed via unsafe code. This means that downgrading a reference to an untyped pointer is very cumbersome, despite being a very simple operation. ## Solution Define conversions for easily and safely constructing untyped pointers. This is the non-owned counterpart to `OwningPtr::make`. Before: ```rust let ptr = unsafe { PtrMut::new(NonNull::from(&mut value).cast()) }; ``` After: ```rust let ptr = PtrMut::from(&mut value); ``` Co-authored-by: Carter Anderson <mcanders1@gmail.com>		2022-11-14 22:53:50 +00:00
