As the title says. Is there a noncopy way to view Vec<u64> or [u64;4] as Vec<u8> or [u8;256] ?
After all I guess it could be made via unsafe block, ptr ... but how?
And maybe there is another 'safe' way?

As that post says, you _almost certainly_ want a `&[u8]` and not a `Vec
`. – Peter Hall Jul 13 '19 at 12:45
