Struct ReplayGuard 

pub struct ReplayGuard { /* private fields */ }

Verifier-side replay memory: nonce to its signed timestamp (ms). Entries older than the window are evicted by timestamp; when the memory is full of live entries a new request is refused, never the whole set forgotten.

Implementations

impl ReplayGuard

pub fn first_use(&mut self, nonce: &str, ts_ms: u64, now_ms: u64) -> bool

Record nonce signed at ts_ms; false when already seen or when the memory is full of entries still inside the window.

Trait Implementations

impl Debug for ReplayGuard

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

Formats the value using the given formatter.
