Global DAP parameters common across tasks.

Fields

report_storage_epoch_duration: Duration

The report storage epoch duration. This value is used to control the period of time for which an Aggregator guarantees storage of reports and/or report metadata:

1. Once an epoch has elapsed, all reports and metadata corresponding to the epoch may be deleted in order to reduce storage costs. In addition, all reports for this epoch will be rejected.
2. Reports pertaining to epochs that have not yet begun may be rejected.

Let now be the current time truncated by the report storage epoch duration. All epochs preceeding the previous are subject to deletion; for all epochs following the next, reports will be rejected:

    now-2 <- reports rejected, data subject to deletion
    now-1 <- start of previous epoch
    now   <- start of current epoch
    now+1 <- start of next epoch
    now+2 <- reports rejected

Thus, storage is only guaranteed for the previous epoch, the current epoch, and the next epoch.

max_batch_duration: Duration

Maximum interval duration permitted in CollectReq. Prevents Collectors from requesting wide range or reports.

min_batch_interval_start: Duration

Lower bound of an acceptable batch interval for collect requests. Batch intervals cannot start more than min_batch_interval_start apart from the current batch interval.

max_batch_interval_end: Duration

Upper bound of an acceptable batch interval for collect requests. Batch intervals cannot end more than max_batch_interval_end apart from the current batch interval.

supported_hpke_kems: Vec<HpkeKemId>

HPKE KEM types that are supported. Used when generating HPKE receiver config.

Implementations

impl DapGlobalConfig

pub fn gen_hpke_receiver_config_list( &self, first_config_id: u8, ) -> impl IntoIterator<Item = HpkeReceiverConfig>

Generate a list of HPKE receiver configurations, one for each element of supported KEM algorithm. first_config_id is used as the first config ID; subsequent IDs are chosen by incrementing first_config_id.

Trait Implementations

impl Clone for DapGlobalConfig

fn clone(&self) -> DapGlobalConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for DapGlobalConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DapGlobalConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
