Struct DtlsReplayWindow 

pub struct DtlsReplayWindow { /* private fields */ }

Tracks a DTLS anti-replay bitmap for one epoch.

Implementations

impl DtlsReplayWindow

pub fn new() -> Self

Creates a fresh replay window with no accepted records.

Arguments

• (none) — This function takes no parameters.

Returns

A new or updated Self value as constructed in the function body.

Panics

This function does not panic.

pub fn check_and_mark(&mut self, sequence: u64) -> bool

Checks and marks a sequence number according to DTLS replay-window rules.

Arguments

• sequence — Incoming record sequence number for this epoch.

Returns

true when record is accepted and state updated; false on replay/too-old.

Panics

This function does not panic.

pub fn snapshot(&self) -> DtlsReplayWindowSnapshot

Returns a copyable snapshot of replay-window state for persistence or transfer.

Arguments

• self: Replay window to snapshot.

Returns

Snapshot containing latest sequence, bitmap, and initialization flag.

Panics

This function does not panic.

pub fn restore_from_snapshot(&mut self, snapshot: DtlsReplayWindowSnapshot)

Restores replay-window state from a previously captured snapshot.

Arguments

• self: Replay window to update.
• snapshot: Snapshot payload to apply.

Returns

().

Panics

This function does not panic.

Trait Implementations

impl Clone for DtlsReplayWindow

fn clone(&self) -> DtlsReplayWindow

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DtlsReplayWindow

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

Formats the value using the given formatter.

impl Default for DtlsReplayWindow

fn default() -> DtlsReplayWindow

Returns the “default value” for a type.

impl PartialEq for DtlsReplayWindow

fn eq(&self, other: &DtlsReplayWindow) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
