Struct HsDirParams

pub(crate) struct HsDirParams {
    pub(crate) time_period: TimePeriod,
    pub(crate) shared_rand: SharedRandVal,
    pub(crate) srv_lifespan: Range<SystemTime>,
}
Expand description

Parameters for generating and using an HsDir ring.

These parameters are derived from the shared random values and time parameters in the consensus, and are used to determine the position of each HsDir within the ring.

Fields§

§time_period: TimePeriod§shared_rand: SharedRandVal§srv_lifespan: Range<SystemTime>

Implementations§

§

impl HsDirParams

pub fn time_period(&self) -> TimePeriod

Return the time period for which these parameters are valid.

The hs_blind_id for an onion service changes every time period: when uploading, callers should use this time period to determine which hs_blind_id’s descriptor should be sent to which directory.

pub fn start_of_shard_rand_period(&self) -> SystemTime

Return the starting time for the shared-random-value protocol that produced the SRV for this time period.

pub fn offset_within_srv_period( &self, when: SystemTime, ) -> Option<SrvPeriodOffset>

Return an opaque offset for when from the start of the shared-random-value protocol period corresponding to the SRV for this time period.

When uploading, callers should this offset to determine the revision counter for their descriptors.

Returns None if when is after the start of the SRV period.
