Struct SlidingWindowDetector 

pub struct SlidingWindowDetector { /* private fields */ }

A replay detector over a monotonically increasing sequence number that never wraps.

Handles the full 64-bit range, which is what DTLS needs. See WrappedSlidingWindowDetector for sequence numbers that do wrap.

Implementations

impl SlidingWindowDetector

pub fn new(window_size: usize, max_seq: u64) -> Self

Creates a detector with a window_size-wide window over sequence numbers up to max_seq.

Does not allow wrapping: it handles monotonically increasing sequence numbers across the full 64-bit range, which is what DTLS replay protection needs.

Trait Implementations

impl ReplayDetector for SlidingWindowDetector

fn check(&mut self, seq: u64) -> bool

Returns true if seq has not been seen before and is inside the window.

fn accept(&mut self)

Commits the sequence number from the preceding Self::check call as received.
