Enum Ttl 

pub enum Ttl {
    Never,
    ExpiresAt(TimestampMillis),
    DurationMillis(u64),
}

Variants

Never

ExpiresAt(TimestampMillis)

DurationMillis(u64)

Implementations

impl Ttl

pub fn expires_at(&self, anchor: TimestampMillis) -> Option<TimestampMillis>

The absolute instant at which this TTL elapses, anchored at anchor, if ever.

Never has no expiry. A DurationMillis whose anchor + duration is not representable in i64 milliseconds (durations beyond ~292 million years) returns None and is therefore treated as non-expiring — a deliberate, fail-open choice for an unreachable boundary.

pub fn is_expired_at( &self, anchor: TimestampMillis, now: TimestampMillis, ) -> bool
