Struct Zeroizing 

Source 
pub struct Zeroizing<Z>(/* private fields */)
where
    Z: Zeroize + ?Sized;
Expand description

Zeroizing owner used for decrypted plaintext and derived CEK bytes. Zeroizing is a wrapper for any Z: Zeroize type which implements a Drop handler which zeroizes dropped values.

Zeroizing<T> is defined with repr(transparent), which means it is guaranteed to have the same physical representation as the underlying type.
