Struct WrappedSlidingWindowDetector 

pub struct WrappedSlidingWindowDetector { /* private fields */ }

A replay detector for a sequence number that wraps at a known maximum.

SRTP’s 16-bit sequence numbers wrap, so the window has to interpret a large backwards jump as a rollover rather than a replay.

Implementations

impl WrappedSlidingWindowDetector

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

Creates a detector with a window_size-wide window that allows the sequence number to wrap at max_seq.

Suitable for the short counters used by SRTP and SRTCP.

Trait Implementations

impl ReplayDetector for WrappedSlidingWindowDetector

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.
