Original data are not actually zeroed

[oblique]

Consider this example:

use seckey::SecKey;

fn main() {
    let buf: [u8; 7] = [1, 2, 3, 4, 5, 6, 7];
    let orig_data = unsafe { std::slice::from_raw_parts(buf.as_ptr(), buf.len()) };

    let sec = SecKey::new(buf).unwrap();

    dbg!(orig_data);
}

Because buf is an array, by moving it, you are actually copying it to another place on the stack. So, original data stay there untouched and never zeroed.

I was thinking that &mut T could be a solution, but this will make SecKey unsafe.
What do you think?

A few years ago I tried to solve this problem with inplace syntax, which has been deprecated.
