Struct ReplayWindow 

pub struct ReplayWindow { /* private fields */ }

Sliding-window replay tracker for a single sequence-numbered stream.

Implementations

impl ReplayWindow

pub const fn new() -> Self

Create an empty window. The first accept call is always accepted.

pub fn accept(&mut self, seq: u32) -> bool

Attempt to accept a new sequence number.

Returns true if the sequence is novel (never seen before AND within the window). Updates internal state to record the acceptance.

Returns false for:

• Exact duplicate of a previously-accepted sequence within the window.
• Sequence below the window (too old).

pub fn high_watermark(&self) -> u32

Highest accepted sequence number. Returns 0 if no packets have been accepted yet (caller should check is_initialized to disambiguate).

pub fn is_initialized(&self) -> bool

Whether any packet has been accepted yet.

Trait Implementations

impl Debug for ReplayWindow

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

Formats the value using the given formatter.
