give an example.

Please clarify what you mean by "align cast".

struct ok {
f: u8
}

struct not{
f: u16
}

fn main (){

 let mut z = ok{ f:4};

// z alignment is 1 byte..
// now what I want is represent z adress to other type with different alignment

let mut x :*not= &z;

That is not guaranteed.

That is instant UB. What are you programming that you need that? Are you translating C code?

If you give us the bigger picture, we may better help you finding idiomatic alternatives.
