Per-task DAP parameters.

Fields

version: DapVersion

The protocol version (i.e., which draft).

leader_url: Url

Base URL of the Leader.

helper_url: Url

Base URL of the Helper.

time_precision: Duration

Report granularity. Used by the Client to truncate the timestamp and by the Aggregators to constrain the batch interval of time=interval queries.

expiration: Time

The time at which the task expires.

min_batch_size: u64

The smallest batch permitted for this task.

query: DapQueryConfig

The query configuration for this task.

vdaf: VdafConfig

The VDAF configuration for this task.

vdaf_verify_key: VdafVerifyKey

VDAF verification key shared by the Aggregators. Used to aggregate reports.

collector_hpke_config: HpkeConfig

The Collector’s HPKE configuration for this task.

Implementations

impl DapTaskConfig

pub fn batch_span_for_out_shares<'a>(
    &self,
    part_batch_sel: &'a PartialBatchSelector,
    out_shares: Vec<DapOutputShare>
) -> Result<HashMap<DapBatchBucket<'a>, DapAggregateShare>, DapError>

Compute the “batch span” of a set of output shares and, for each buckent in the span, aggregate the output shares into an aggregate share.

pub fn batch_span_for_sel<'a>(
    &self,
    batch_sel: &'a BatchSelector
) -> Result<HashSet<DapBatchBucket<'a>>, DapError>

Return the batch span determined by the given batch selector. The span includes every bucket to which a report that matches the batch selector could be assigned.

pub fn batch_span_for_meta<'a>(
    &self,
    part_batch_sel: &'a PartialBatchSelector,
    report_meta: impl Iterator<Item = &'a ReportMetadata>
) -> Result<HashMap<DapBatchBucket<'a>, Vec<&'a ReportMetadata>>, DapError>

Return the batch span of a set of reports with the given metadata.

Trait Implementations

impl AsRef<DapTaskConfig> for DapTaskConfig

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for DapTaskConfig

fn clone(&self) -> DapTaskConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'de> Deserialize<'de> for DapTaskConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DapTaskConfig

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

Serialize this value into the given Serde serializer.
