Type Alias CloneIntoFn 

pub type CloneIntoFn = for<'src, 'dst> unsafe fn(source: PtrConst<'src>, target: PtrUninit<'dst>) -> PtrMut<'dst>;

Function to clone a value into another already-allocated value

Safety

The source parameter must point to aligned, initialized memory of the correct type. The target parameter has the correct layout and alignment, but points to uninitialized memory. The function returns the same pointer wrapped in an PtrMut.
