Implementations

impl HypothesisLedger

pub fn new( groups: Vec<HypothesisGroup>, membership_events: Vec<HypothesisMembershipEvent>, selection_events: Vec<HypothesisSelectionEvent>, ) -> Result<Self, KnowledgeError>

pub fn groups(&self) -> &[HypothesisGroup]

Return validated groups in canonical order.

pub fn membership_events(&self) -> &[HypothesisMembershipEvent]

Return validated membership history in canonical order.

pub fn selection_events(&self) -> &[HypothesisSelectionEvent]

Return validated selection history in canonical order.

pub fn group_fingerprint( &self, group_uuid: Uuid, ) -> Result<[u8; 32], KnowledgeError>

Canonical fingerprint over one exact immutable hypothesis group.

pub fn membership_fingerprint( &self, membership_event_uuid: Uuid, ) -> Result<[u8; 32], KnowledgeError>

Canonical fingerprint over one exact membership event.

pub fn selection_fingerprint( &self, selection_event_uuid: Uuid, ) -> Result<[u8; 32], KnowledgeError>
