espresso_types::v0::impls::committee

Struct Inner 

Source 
struct Inner {
    non_epoch_snapshot: NonEpochSnapshot,
    snapshots: BTreeMap<EpochNumber, EpochSnapshot>,
    all_validators: BTreeMap<EpochNumber, RegisteredValidatorMap>,
    da_committees: BTreeMap<EpochNumber, Arc<DaCommittee>>,
    first_epoch: Option<EpochNumber>,
    fixed_block_reward: Option<RewardAmount>,
}

Fields§

§non_epoch_snapshot: NonEpochSnapshot

Captured pre-epoch view.

Built once at constructor time. add_da_committee operates on the per-epoch da_committees map and does not modify the pre-epoch view.

§snapshots: BTreeMap<EpochNumber, EpochSnapshot>

Per-epoch snapshots.

Each mutator rebuilds the snapshot for its affected epoch(s).

§all_validators: BTreeMap<EpochNumber, RegisteredValidatorMap>

Holds the full validator candidate sets temporarily, until we store them.

§da_committees: BTreeMap<EpochNumber, Arc<DaCommittee>>

DA committees, indexed by the first epoch in which they apply.

Kept separate from snapshots because the lookup is a range query.

§first_epoch: Option<EpochNumber>§fixed_block_reward: Option<RewardAmount>

Fixed block reward (used only in V3).

Starting from V4, block reward is dynamic

Implementations§

Source§

impl Inner

Source

fn resolve_da_committee(&self, epoch: Option<EpochNumber>) -> Arc<DaCommittee>

The DA committee that applies to epoch, or the non-epoch fallback when epoch is None or no explicit DA committee covers it.

Source

fn epoch_committee(&self, e: EpochNumber) -> Option<&Arc<EpochCommittee>>

Borrow the per-epoch EpochCommittee if loaded.

Source

fn address(&self, e: EpochNumber, key: &BLSPubKey) -> Result<Address>

Source

fn active_validators(&self, e: EpochNumber) -> Result<AuthenticatedValidatorMap>

Source

fn put_epoch_committee( &mut self, epoch: EpochNumber, committee: Arc<EpochCommittee>, )

Source

fn put_randomized_committee( &mut self, epoch: EpochNumber, randomized: Arc<RandomizedCommittee<StakeTableEntry<PubKey>>>, )

Rebuild the snapshot for epoch with a new randomized committee, carrying forward the existing committee/da. No-op if no snapshot for epoch exists yet.
