Struct ExpiryUpdate 

pub struct ExpiryUpdate {
    pub target: ExpiryTarget,
    pub max: Option<Duration>,
}

An expiry target and optional limit on the remaining lifetime it requests.

The limit is measured from the operation’s access_time, regardless of the target’s anchor. It does not change the policy kind or shorten existing deadlines. Repeated updates can therefore keep an object alive indefinitely.

Fields

target: ExpiryTarget

The requested minimum deadline.

max: Option<Duration>

Maximum remaining lifetime. None means no limit.

Implementations

impl ExpiryUpdate

pub fn resolve( self, time_created: Option<Timestamp>, access_time: Timestamp, ) -> Result<Option<Timestamp>>

Resolves and validates the requested deadline using the stored object metadata.

Returns None if the creation-time anchor is required but unavailable.

Returns ErrorKind::InvalidMetadata if the requested deadline exceeds access_time + max, even if the existing deadline already satisfies it. Timestamp addition rounds up to seconds and saturates at the supported maximum.
