Struct FixedNoClone 

pub struct FixedNoClone<T>(/* private fields */);

Non-cloneable stack-allocated secret wrapper.

This is a zero-cost newtype over Fixed<T> that deliberately omits Clone and Copy. Use this when you want to enforce single-ownership and prevent accidental duplication of secrets.

Converts from Fixed<T> via .no_clone().

Examples

use secure_gate::{Fixed, FixedNoClone};
let secret = Fixed::new([1u8; 32]);
let no_clone: FixedNoClone<[u8; 32]> = secret.no_clone();
// no_clone cannot be cloned
assert_eq!(no_clone.expose_secret()[0], 1);

With zeroize:

use secure_gate::FixedNoClone;
let mut secret = FixedNoClone::new([1u8, 2, 3]);
drop(secret); // wiped on drop

Implementations

impl<T> FixedNoClone<T>

pub const fn new(value: T) -> Self

Wrap a value in a non-cloneable fixed secret.

Example

use secure_gate::FixedNoClone;
let secret = FixedNoClone::new(42u32);

pub const fn expose_secret(&self) -> &T

Expose the inner value for read-only access.

pub fn expose_secret_mut(&mut self) -> &mut T

Expose the inner value for mutable access.

pub fn into_inner(self) -> T

Consume and return the inner value.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

Available on crate feature zeroize only.

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
