Struct seckey::TempKey

pub struct TempKey<'a, T: ?Sized + 'static>(_);

Temporary Key

use seckey::{ TempKey, CmpKey };

let mut key = [8u8; 8];
let key = TempKey::from(&mut key);
assert_eq!(CmpKey::from(&*key), &[8u8; 8]);

Note

• It will zero the value when Drop.
• It will refuse to accept if T is reference or pointer, to avoid causing null pointer.
• It is a reference, to avoid it from being affected by stack copy (return value).
