Trait ZeroizeOnDrop 

Source 
pub trait ZeroizeOnDrop { }
Expand description

Marks a type that erases its contents when dropped.

Implementors must provide their own Drop implementation that calls Zeroize::zeroize. This marker generates no behavior and does not enforce that requirement. It expresses a policy for types that know they hold secrets, rather than for general-purpose storage types.

use tc_zeroize::{Zeroize, ZeroizeOnDrop};

struct Secret([u8; 32]);
impl Zeroize for Secret {
    fn zeroize(&mut self) {
        self.0.zeroize();
    }
}
impl Drop for Secret {
    fn drop(&mut self) {
        self.zeroize();
    }
}
impl ZeroizeOnDrop for Secret {}
let _secret = Secret([7; 32]);

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
