Trait ZeroizablePrimitive 

pub trait ZeroizablePrimitive: Copy + Sized {
    const ZEROED: Self;
}

A Copy type whose all-zero value is meaningful and valid, so that a Secret of it can be default-constructed in a zeroed state.

This is used instead of Default for two reasons: it lets Secret::new produce a zeroed value at compile time via an associated const, and – crucially – it works for arrays of any length, whereas [T; N]: Default is only implemented for N <= 32.

Required Associated Constants

const ZEROED: Self

The zeroed value of this type. This needs to be a valid static instance of Self that Secret::zeroize will internally convert into a byte array and use to overwrite the memory location of the given instance of the primitive.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
