Struct RekeyState 

pub struct RekeyState { /* private fields */ }

Available on crate feature crypto only.

Tracks the current key epoch and when rekeying is needed.

Implementations

impl RekeyState

pub fn new() -> Self

Create a new rekey state starting at epoch 0.

pub fn epoch(&self) -> u32

Get the current epoch.

pub fn send_count(&self) -> u64

Get the send counter for the current epoch.

pub fn recv_count(&self) -> u64

Get the receive counter for the current epoch.

pub fn increment_send(&mut self) -> Result<u64, CryptoError>

Increment the send counter.

Returns the counter value to use for this message.

Errors

Returns CounterExhaustion if the counter has reached the hard limit.

pub fn record_recv(&mut self, counter: u64)

Record a received message counter.

Note: Actual replay detection is handled by the replay window.

pub fn should_rekey(&self) -> bool

Check if we should initiate a rekey (soft limit reached).

pub fn keys_expired(&self) -> bool

Check if the current keys are expired (hard limit reached).

pub fn can_rekey(&self) -> bool

Check if we can perform another rekey (epoch limit).

pub fn advance_epoch(&mut self) -> Result<(), CryptoError>

Advance to the next epoch.

Resets counters and updates epoch start time.

Errors

Returns EpochExhaustion if the epoch counter has reached the limit.

Trait Implementations

impl Debug for RekeyState

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

Formats the value using the given formatter.

impl Default for RekeyState

fn default() -> Self

Returns the “default value” for a type.
