Struct DekMessageCounter 

pub struct DekMessageCounter { /* private fields */ }

Per-DEK message-count metric.

Warn at 2^30 messages, force rotation before 2^32 (well clear of the birthday bound). Observed backends plug into arkhe_runtime_dek_message_count{user_id}.

Implementations

impl DekMessageCounter

pub fn new(dek_id: DekId) -> Self

New counter — keyed by dek_id.

pub fn dek_id(&self) -> DekId

DEK id.

pub fn count(&self) -> u64

Current count.

pub fn record_message(&mut self)

Called on successful encrypt — count += 1.

pub fn rotation_trigger(&self) -> RotationTrigger

Rotation trigger decision. 2^30 warn / 2^31 force.

Force threshold set at 2^31 — clear margin before the 2^32 birthday bound (~50% earlier trigger).
