Struct ReplayWindow 

pub struct ReplayWindow {
    pub last_accepted: u32,
    pub last_accepted_time_ms: u64,
    pub backward_bitmap: u8,
    pub recent_mics: Deque<RecentMic, RECENT_MIC_CAPACITY>,
}

Replay-detection window for secure traffic from one sender.

Fields

last_accepted: u32

Highest accepted frame counter.

last_accepted_time_ms: u64

Timestamp of the highest accepted frame.

backward_bitmap: u8

Occupancy bitmap for the backward counter window.

recent_mics: Deque<RecentMic, RECENT_MIC_CAPACITY>

Accepted MICs retained for duplicate late-arrival checks.
