Struct NoProtection 

pub struct NoProtection;

Zero-overhead default. sign returns 0; verify always succeeds. The optimizer reliably folds calls through NoProtection into no-ops in release builds.

Trait Implementations

impl Clone for NoProtection

fn clone(&self) -> NoProtection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NoProtection

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

Formats the value using the given formatter.

impl Default for NoProtection

fn default() -> NoProtection

Returns the “default value” for a type.

impl FreelistProtection for NoProtection

fn sign(&self, _next_idx: u32, _slot_addr: usize) -> u32

Sign a freelist link. next_idx is the 1-based slot index being stored, or 0 for the end-of-list sentinel (so the input range is 0..=u32::MAX). slot_addr is the virtual address of the slot containing the link (used as a nonce so that a copy of a freelist link to a different slot won’t verify).

fn verify( &self, _next_idx: u32, _stored_mac: u32, _slot_addr: usize, ) -> Result<(), FreelistCorruption>

Verify a stored MAC. Returns Ok(()) on a valid link, Err(FreelistCorruption) on a mismatch.
