Struct ReplayWindow 

pub struct ReplayWindow { /* private fields */ }

A wide sliding replay window over a monotonic u64 counter using a circular word ring.

Implementations

impl ReplayWindow

pub fn new() -> Self

Create a replay window with the default HighThroughput profile (16 KB / 131,072 bits).

pub fn new_with_profile(profile: ReplayProfile) -> Self

Create a replay window configured with a specific sizing profile.

pub fn profile(&self) -> ReplayProfile

Current sizing profile of the replay window.

pub fn promote_to_high_throughput(&mut self)

Dynamically promote window capacity to HighThroughput (16 KB / 131,072 bits). Preserves all previously seen counters without dropping replay protection.

pub fn check(&self, counter: u64) -> bool

Would counter be accepted right now? Read-only — does not mutate state.

pub fn commit(&mut self, counter: u64)

Record counter as seen, advancing the window. Must be preceded by check().

pub fn check_and_set(&mut self, counter: u64) -> bool

Convenience helper to check and commit a counter in one step. Used by test harnesses and benchmark suites.
